and then we're good so we mean when we talk about the muscles that move the extremities around I kind of like to group the muscles into first like muscles that anchor the shoulder blade and the upper extremity ain't gonna shoulder blade to the chest that's that's one set of muscles that we're going to look at and then the second set of muscles they're gonna look at other ones that anchor the arm attach it to the shoulder blade by going over to my clinic I always say that the arm is attached to the shoulder blade and shoulder blades anchored to the ribcage and anywhere along the line you can get injured and so we got a look at all the different pieces and so from an understanding perspective it's like you know who's moving whom around versus just a list of muscles so this way we sort of make sense of of it so we group them so the first group is two shoulder blade to the chest get that arm anchor to the axial skeleton and then get that our tank attached to the shoulder blade so he holds all do it it doesn't fall out and then after that we're gonna have moving things and and moving things are up here pulling things down here moving things and then we go down to the wrist moving things we don't really do fingers conceptually right there at that point so the first couple of pictures we have are just sort of overview pictures they're pretty nice pretty good at the store I mean if you know all these muscles in your pop you know all the muscles you might do a few extra but you know there's more detail but we don't really go that deep in here well let's get started so first we're gonna start up in the ribcage area and we gonna basically go through muscles here you can see that we got to go through muscles in the back in the back then you see the shoulder blade is anchored to the to the rib cage back here so we've got a copper three muscles here and then we gonna definitely talk a little bit more about the trapezius that holds the shoulder blade into the neck area and into the spine here and then after that we're gonna have muscle also up here that brings the shoulder blade from the altar inside and anchors it that way up to the rib cage and and also from the car car here those down the bankers it that way to the rib cage so we have multiple anchors that way so that's what we start with so the first one of my favorites is the levator scapulae and if I want to visualize to leave a the scapula actually I gotta go and look at this thing here but I can't even see it on here so it's a little hard to visualize that muscle but it's a really really important muscle it comes from the tip of the shoulder well not to take the inside ankle or the shoulder blade and it reaches up and goes to the top vertebra in your neck you see right here the tip of the shoulder blade and then you disappear stab but you can see here it goes to the first four parts of the neck right there on the side very deep very thick muscle so if somebody looks right I thought this is the boss who's mad at me possibly so that's that one for me so the elevates the scapula it rotates the glenoid cavity down what that means is when this pulls on it you can see how that you can sort of visualize that pulls up and then that rotates downward and that's the glenoid cavities of the glenoid cavity will go down that's what that means well technically the medial border of the scapula at the superior angle that's right in here at that muscle I always look at that muscle that's a pretty much a given if somebody has trouble up here at a car accident or something their shoulder walking there is something going on with this and very awfully to act up as a neck pain on top you touch it it's like oh that hurts then you like start thinking about that yeah I know the scalloped and that's from we're going really high up with this is not okay so you know so it's from here then this is going up here that was that we made a scapula and then and then as we go down on the shoulder blade began to the next set of muscle down here who kind of reach into the spine as spinous process and those are the rhomboids and the rhomboids go from the medial border of the shoulder blade into the spinous process Espeon spinous process and it does the same it ad ad dumps the shoulder blade the scapula so it will pull the shoulder blade closer to the midline so you doing this kind of stuff you see it here hope it falls on out and again it will also as it pulls up here the glenoid cavity will reach downward so the glenoid cavity goes down so if we do this kind of motion those those muscles help up those muscles also those are not prime motions but they're important and again these pictures here where there is red zones and then axis on the debt those are trigger point jobs those are pressure points and those are pain areas that these muscles getting to it's not always but very often you get help like you think something you know tiger balm or whatever cream or an icy heart or soul brought something that key top is capsaicin afterwards and you massage the ceiling somebody do a little Chris Brooks you get a little bit of squeezing what you do is you squeeze the blood out of the muscle in your squeeze that's that one of the techniques and that often feels much better the problem is then the next day is now can you do it again angry trapezius we mentioned that most already it starts all the way up on it answer on the top of the EOP Goes Down all the spices down to t12 that's right here by the ribs that's really low that's a large muscle but all the way down and then it reaches out to the the programs minus capital on the third of the class but basically it it goes around from the back a little to the program and then to the front on the model here it reaches around this way so it sort of grabs it but it's a skinny muscle it's not I guess this muscle we can we can outline here on the model here it's this muscle right here so that's where I tagged it most likely if I'd use that as a muscle it's it's an important muscle it has a lot of functions look at this functional eyes and stabilized raises retracts the scapula well you just think of all these different ways this Muslim can pull on that shoulder plane then you kind of call these different functions it rotates the glenoid upward in extents and also rotates to have me dip down a little bit last one I know last week from Wednesday look at the paint pattern that means muscle could get lots of paint patterns Janet Geralt describes that muscles she's Jonah's Canada's physician who did a lot of work with myofascial pain and all that sort of chronic pain stuff very good a cool lady and she said if somebody has a heavy purse here or heavy coat that strange muscle keeps people and giving people headaches but that's a very very cool to work with somebody who has a problem as an initial leg let's see if we can help something with headaches and then so those are the ones sort of in the back the back the top that overlaying and now we're going to go to one that's in the front and that muscle starts this is a scapular that's retracted reflected back so if you look at here that would be like pulled that way and so it shows the muscle starts on the inside that's like inside hearing where it starts and it reaches around the ribs and holds the ribs like finger or like when you actually trace it you can think that's a serrated knife not a flat knife mr8 enough so that's what I call that serratus as an awesome less than a serratus anterior that's the one on the front so so on it comes out like that you could see them sports that like boxing that Porsche log that these muscles need to be very strong because they really pull that shoulder blade into the chest so it doesn't just fly backwards when you get a very very interesting bolts are very involved I mean who is in so when you go like that them on the side that's where that most languages and the reason why it is very involved is like let's say for example you were holding the steering wheel and you have a car accident and you get holding on the steering wheel you can slap from behind you go like whoa but it just reaches all back everything gets pushed back up a little violent today I guess huh and and this soul blade gets yanked backwards and you can just see how that sprains these muscles and so all that kind of stuff or even just holding it up long they can do a lot of that it's interesting when I then I you know you think about when you think about Alex most people especially me get older that the shoulders sort of comment a little bit and they come forward a little bit so to be caving in a little bit and then at some point I start realizing it's like well you know our arms are always hanging down that's always pulling on anything it's like guevara dog the stuff is always pushed off we were quadrupeds we weren't always bad I mean depends on who you want to talk to her but for most of us that sort of in science that's kind of how close we came from the four-legged stood up and the force from hanging out there pushing and it's a very different force so this muscle is interesting when you think of how it has to hold the chest inward and upward versus also the shoulder blade down it towards the chest but also in the chest is at the full length doesn't have to have it fall down so one of the things I do is that when I go walking or hiking I have ski poles with so I push I do four basic would be like be a little dog but push down to is not just all hanging down so all these muscles get strengthened by that and I'm at a guy at Schiphol Park where I go hike he's 93 or 94 and he's like oh yeah can we pose - what I'm like yes I do and he's like you know first I thought it's just for my balance but now my shoulder don't hurt no more and I'm like great that's very good so so that muscle is definitely working with that so it goes from that anterior board as a shoulder blade this gap to the rib it won't do eight we want to know where it is we got that you know name it we don't have to know all the details for the test that's just to understand and then ladies go back so on the model these are the serratus anterior and if I one that has a hook on top that goes together like that you can see how they common in like so let's see that brings us then to I would think yeah PEC minor and not according to the process and reaches down and pokes you lose her stare and that also goes right from that point from the front of the shoulder blade into the ribs and some of the reaches down this way and stabilizes a short way from the front so that's more stabilized i thicken it the coracoid rate depressed and rotated shoulder blade down and pulling forward and also elevate the ribs if you breathe deep so it can pull the roots upward so it's from that perspective it could be considered an inspiratory nose okay so with that does that make sort of sense those are the shoulder blade muscles to pull the shoulder blade in the chest now we're going to go and attach the arm to the shoulder blade we don't move them we just attach them those muscles are known as the rotator cuff muscles some people have rotator cuff tears frozen shoulder here a frozen shoulder yeah that kind of stuff stopping him take the capsule but it's often a supraspinatus tab so those muscles the rotator cuff they're also called 6si t is that's ideas that's an acronym for all the muscles that are making damaged rotator cuff oh so there's four of those muscles that do that and they all reach from the shoulder blade three from the backside and one from the front side and reach on to the numerous and hold it three on the greater tubercle one of the lesser two and pull it in to the plane of the cabin there's a lot of wear and tear that think about so we want three on the back so now this is where you have the spine of the scapula and then on top you have two supraspinous fossa and now we call it the supraspinous muscle I mean superspinatus muscle that's it sit that's one of them that's the first s supraspinatus then we go below that and this is the plant this is from the back to the spine and you see the spine of the scapula you know it's from the back no spine of the scapula from from so below you now that's the in front spine 8as muscle in sitting in the infraspinous fossa that's the eye infraspinatus and then we got a little sliver of muscle here on the longer side that comes in feeds in as well and they call that the teres minor muscle that's the name you have to study teres minor that's the T and then we flipped the scapula over and see it from the front and underneath we got the salt scapular fossa and down there we have them also called the subscapularis muscle there we go so that's sort of helpful so let's see where do we have them we have a big old supraspinatus infraspinatus teres minor on the model actually on your table let's go to the model on your table you're lookin well actually take this did this first one off but then underneath you see here you see the spine of the scapula on top you see a ball chasm also down below you see a muscle the top one is the supraspinatus the bottom one is the infraspinatus then the last portion of that sliver there is two teres minor and in on our model we have one more below that we'll talk about that in a little bit we haven't touched that one yet so supraspinatus infraspinatus teres minor and then I flip it over and blow here I have to solve scapularis muscle then you look at so all the muscles in the back they will go to the greater tubercle and at one muscle in the front of the subscapularis the main function of all those four is stabilize the shoulder joint we also don't and I don't know why is not wasted oh man please listen to me introspection yeah they're almost the muscles in the back especially the infraspinatus but also the Terra so on the super so on a definite the teres minor they rotate the humerus laterally so what does that mean when I do this motion and I turned the upper arm out so when the form goes out the upper arm turns out that is taught by these muscles back here so that's one motion that they knew so somebody have to strengthen the those muscles back there because it's very common injury they take a rubber band or sewing fool this way into those then they flip it over and go inward because the subscapularis muscle there is the subscapularis comes from the inside and reaches to the humerus there that's from here to here when you pull in a from a gonna do this to the noise so the internal rotation but the main function and that's right here video and in internal medially that's the same but the main function of all of them is stabilized to show the job one more thing that the super spending is tough and yes they're wrong this is if you think that muscle sits right on top here and goes right to to here it also pulls to your man over there so that's called abduction initial abduction so what happens there is kind of interesting because now what we can do is we can actually put this monster on top again put this muscle top in there put it in again and so when you look at the muscle on top of the shoulder the supraspinatus reaches right to the greater tubercle so you can pull this arm nicely out a little bit it's ready just blanks on that a little bit and then we got this next muscle that I want to talk about which is hopefully developed oh let's see yeah almost here we go listen ex mostly I'm going to talk about because that seems on top of the supraspinatus and reaches around the arm and holds the arm like you know a shoulder all the pocket holes you own but it's attached right here and reaches down so it's attached at dad like the trapeze is actually under the shoulder blade the spine of the scapula they're coming and then the front and reaches straight down to the deltoid tuberosity that's a bulb that won't we learn that's that one of the deltoids and so as that reaches straight down if if it wants to do its function and it's one of its main functions is actually bring your mouth adoption of the are the same as this top one but it's angled so really that if this contracts right here all its gonna do it's going to pull your mop like that so the arm first needs to be brought to about this level and then this must look and function so the supraspinatus and that next muscle were very nicely together if you can see in that function that motion and clinically that is very interesting because if you have the rotator cuff tear or a frozen shoulder very most likely this system also the supraspinatus and then you've got people walking around and they can't leave the arm up like that they just do this that muscle don't work just dis more works and so they have to push it out that way and then they can raise it so once you know a little biomechanics it's kind of interesting that way you can sort of piece it together all the time what is what so we might as well just go right here and finish this one because this now is the group of muscles that moves the upper arm so we finished acid's the supraspinatus infraspinatus teres minor and subscapularis that hold the shoulder into the shoulder blade and now we're going to start moving that around so again we got muscles in the front of muscles in the back that do some other function the deltoid is one of those main functions actually because it's an interesting one in traps all the way around from the front to the back like the trapezius and then it reaches into the arm from different angles so the abduction motion to bring in your mount motion that's one one of the functions but it's also going to bring it on forward a little bit or you bring your backward a little bit depending on where it moves so unweighted that I figured out motions or actions in a muscle is I visualize or feel on a bottles burners the muscle attached and then I feel like what's gonna happen in contracts or even on myself like okay it's here what happens when that contract so it goes off like that so then I know the motion an arm also a big auto muscle that moves to humors around is the one in the front is the pectoralis major most so we have to pack minor going from the coracoid to the ribs now we have one that's on top of that a big one it's a major that muscle goes from the front from the ribs disturbin and the clavicle all the way here and reaches into the arm into the intertubercular groove of the universe so that's right in between the bones between the two buckles so you see that like that so what is it gonna do it's gonna do this it's going to add docked to arm the humerus so that's bringing it in and medially rotate bringing it forward that way if you visualize where a very cool spot that's a cool muscle that's the most as the guys like to make big in the gym because you can see them you know like the rock you know that kind I know that's what a bounce comes they they don't have mirrors in the back so you're looking from the back is always just bit don't see it I hope these days but next muscle is another one that starts at the car card process and goes now into the arm and here we going to the shaft of the humerus so from here to about here mainly what it does it brings down four that's flexion flexion of your own actually flexion of the humerus and a little and add options while bringing it in open it coracobrachialis there's a lot of muscles that have a vertebrae cueing it rim arm break you at Dakshin adds the arm to the body abs do so I just know the a deduction so it's adding when you and then add with the opposite and after about ten years it was natural it's one of those we was violated you know the words I don't know what I chose that word is kind of goofy which is the one letter difference like really look at this guy these guys also want to go not just him but he's huge and so the next muscle is is the latissimus dorsi that's deep here we got the peg in the front in the back we have the muscle that reaches all the way out from the what are we doing here from the spinous process of the thoracic spine law correspondingly impressive record more foul holy cow that's everything down here there's a new promotion all this stuff down in here is what we're talking about all that fascial almost April fascists down here and I buy one today something happened won't you so that's that's the swimmers muscle as we can see it goes into the intertubercular groove of the humerus it's like the PEC just not fooled back it goes back in there wraps on the inside around so when you do this motion oh it's perfect that's the crawl that's the fly extension adduction of media rotates in the ORS extension adduction medial rotation perfect for the crawl that's why it's so big then you think if you think you can visualize maybe maybe you have a muscle come up like that and it pokes this shoulder blade you might get one that attaches right at the shoulder blade that then goes into the same place to help it so we have that pair it's major muscle that goes together with the latissimus stores I'm also into the same place in the tubercle of the humerus and sort of helps it so now we have one that comes all the way up all the way up in here and one that starts here and goes into the same place that's cool so there's the teres major that's why whenever you have something like a Teri's money classical there must be some major if there's a mine there must be a you know maximum there's a minimus and that kind of stuff so you synergies to the latissimus dorsi muscle and now we still move with the elbow around so we're sort of got this taken care of here more or less the back we move the arm we can move the shoulder blade goes into the body and now we can start this Dumpty so we basically have this motion like stiff extension and then we go for on the stuff going on at that point is pronation supination and recess placement Spanish so the biceps brachii by means tooth set means head so this is a muscle that has two starting points some muscles started more than one place they usually anchor in one place well that's actually not intrusive ever money but biceps brachii starts one at the coracoid process look at that in order well we've got three muscles started there - by PEC minor the coracobrachialis and the biceps brachii no wonder it hurts when you poke and it starts there and from there it goes down to the radio and bra city actually that's why I make you study the radial tuberosity that's like that foam right here the forearm right here that bump that's the radial tuberosity well you stress them you tell them you've got to do some work you probably because I need to lift this dumbbell all right I look dumb no no but you know it's it's it's the use you you build muscle you're fairly fast actually I don't know how fast but fairly fast could you lose muscle I know a 10% and then if you don't use it at all if you just lay down and not do not nothing not like a coma then it's like 10% a day I mean it's fast man I see we know is that he's always fun waiting in the office and you have patient face up and you serve so how are you doing and what are the activity was like oh I'm I'm active when you poked at her thighs and like I feel the bone and then you get the older people you gotta be tough you gotta make them get food because that's the stuff that goes if you cannot squat you don't you don't have to be any bulky things but you can differentiate you can like you can feel if the most like flattened and other thing and it's mostly with the old people because then you really these are the most so that's most anti-gravity muscle these two bob muscles of the calf if they go too much then you can't stand up and that's the problem that's by squatting it's one of the most important exercises anyways where we are OPM you know so anyway we go from the coracoid and then the second one comes from the supraglenoid tubercle where is that that's right that's from right up here the glenoid cavity is that little of small round structure on the shoulder blade that the humeral head fits in and on top that's the to problema tool so the biceps cards from there and from there and reaches down to the forearm to the radial tuberosity that's that bump here so it does this motion that's nice it also though when the arm is down pronated this is rotated it uses and turns it up here towards the most around so it's super nice so it's a strong super nail that's that much biceps break yeah our knees the biceps brachii you didn't know we have that we have a brachialis so biceps brachii is around here on top let's take this belt all right the biceps brachii is right biceps is right here you take it out and underneath that we've got the brachialis muscle brachialis muscle just parts of the shaft of the humerus and it goes to the over the coronoid process which is the app and active proximal no I don't make you study that term that's right here so now we go to muscle here we go to muscle here we go the new here and here you go ooh that's real strong that that most of the gist places if you see the biceps goes from spans two joints so there's much more motion with all that corn arm as we staple as a stabilizer synergistic motion but the brachialis only goes from here to here that's motion so that's the various in a simple nor but very strong force the deeper them also towards the ball the more fundamental its motion it's the most superficial the most of the morning you know that makes sense otherwise you couldn't layer the other way around you can't have the muscles that move everything around be at the bottom and then the small so that's the brachialis and look at that we go loroco breakdowns biceps brachii brachii group brachialis now we go break your radius and honor that also still flexes the elbow however that muscle is like in the forum we're thinking that thing is in the forum that muscle starts down here at the distal end of the humerus actually goes almost to halfway and then it goes to the stylus process a styloid process on the radius radius is to thumb right here it goes right there so it does this that's the motion that is actually the muscle from an anatomic from looking place that brings us to the forearm from where you kind of see it as the belly of the muscle and and you look at when you're looking at your dolls from the forearm one thing and the light monkey bar is at fault so you follow the thumb up and the brachial radialis is to the top muscle that goes on that line and that line actually being the top part of the head the dorsum of that versus the palm of them we have these what the muscles are front to back company and so let's see if we actually get there yet no no not yet we go home over here the big one in the back you should of course the one that does this so we have also stuff flexed not in form an extent you know and that's the triceps brachii try these three three heads so this muscle on the backside is sorta like the brachialis and divisive spray jet together just a big job so it starts looked at infraglenoid tubercle of the humerus that's not the one on top that's the one on the ball eight from in sport shaft of the humerus so we were three heads they go from here and then also from here and the shaft of you is an anchor into the olecranon process which is the tip for the elbow right there so this tendon is really springing it is like you say you know there's something wrong with this so that's the triceps brachii and on the model it's just the water in the back there you go now to get to the forearm awesome so look at that so when we look at the muscles in the forearm we really did forehead shape between the flexors in the front the front ones and the bad ones so we already talked about the brachioradialis that comes up from the phone and reaches all the way up that's the differentiating line sort of between the front and the back the way I see so now first we go to the front the palm side and in a palm side we're going to go to four Oscars there's more muscles underneath but do not worry about that yet so the four muscles are like here here either and here that's pretty good of course it's the wrong sign see that it's the wrong side they always do that that models are the features are not in the right place so I'm gonna explain them here and then go to the model because this is kind of indicating all the names so I'm starting all these four apostles that we're studying and this by the way is supposed to be the brachioradialis okay so that's that differentiating but all those muscles that that we study in the forum they all start at the medial epicondyle the medial epicondyle and then they go to various places so we go for we go one is called the pronator terrorism then go the flexor carpi radialis then we go up the palmar is loans and then gonna flexor carpi ulnaris all these names the pronator teres is the emotion descriptive muscle it pronates default so the pronator teres does this to the pot so that muscle we go back to it here starts at the medial epicondyle like everybody else also a little bit here but we don't gonna worry about that and then it goes to the radius so it goes from here we do at Picanto which is right across to the radius and so when it contracts it got to do this we've got to pull the radius over which is pronation so that's the first like your pronator teres and then a next one goes again from the medial epicondyle - this is the foam side I caught the picture maybe it was calling for it this year supposed to be a thumb that's a and this is a little okay so the next one it goes from the medial to the thumb side into one of the one of the metacarpals one of these bones in here we're not gonna worry about that because everybody goes to the south side of the wrist we call that also the flexor that's a function benster is this way Karp really goes to the carpals radialis it goes to the thumb side that's this long wall so it was not that long then the next one we're gonna have again starts right at the medial epicondyle and goes right down the center of the palm actually if you do this use your palm you see it stick it up did you see if you have it some people don't have it then you don't have to study so you better check so if you do this it sticks out because it's the most superficial tendon that basically those this does this to the to the wrists that muscle is known as the palmar is long it's because if the most that goes right nice into the palm of the hand right here it's very skinny and on the far outside there the last one that we study is known as the flexor carpi ulnaris again medial epicondyle it goes through the wrist on the pinky side that's the all no side so we call it the flexor carpi ulnaris so how you gonna study this stuff so you're going to take them to vamp of your thought and put it right in the middle at the condom and then lay down the things there you got one vehicle right across that's the prorated tennis the next thing is goes to the thumb that's the flexor carpi radialis then an X figurative ring finger straight to the into the middle that's the palmaris longus and the last one laying down goes to the outside for the pinky that's the flexor carpi ulnaris and then we have the mnemonic we call it p @p f prominent areas flexor carpi radios pose flexibility there's a chiropractic school training well maybe no and then then you take the model and the model is different in the picture so now we're going to the last element not the right off and then you're running on the test rather you do this you're like oh yeah for later Terry's flexor carpi radialis palmaris longus flexor carpi ulnaris that's about deep as we go go and then when you take it off underneath you know you have a whole bunch of other muscles but those are actually the ones that move the fingers so if you if you ever I don't know if you do a social have mascot more social people squeeze this here if your fingers start moving so most of the inner movers are actually up here we've got a flexor digitorum performed the superficiality for folders and and then you've got the deep for muscles in here and even in the palm you've got tons of muscles in the palm it's good we don't have to start your little thing but next time when you do when you come to bio - if you do that class then you're ready for it because you understand this level right all right does that make some sense first time around we'll think of it we'll do it to get it laughs and then be good oh then we go to the other side almost forgot the other side that's the extent Society that's the one on top so let's see we got em all so we've got one right here let's see if we can make this a little bigger no we can make this video on the top side on the top side I wanted to start III muscles not foremost and the three muscles I want you to study look at these names extensor carpi ulnaris extensor carpi radialis the same thing except it's not flexors extensible so when I would with emotion that these muscles too long to the front flex that's flexion go on to the back extended pull the respect off flexion is bending the wrist border extension is bending it back so those muscles for us they all start and the lateral epicondyle you see their lateral epicondyle is the wrist extensors medial epicondyle wrist flexors so they all start out here they don't start here in the midline they start here on the outside so now I only have to differentiate three of them one on there goes to the thumb and one that goes to the pinky and another one on top the extensor carpi ulnaris would that go to the pink of the thumb the pinky so that's right out here goes to the base of the fifth metacarpal yeah that's the web then so that's on the outside here and then we got one on the inside that goes across right here actually there's two of them days along was in the BRABUS but Rich's mean they make it one of them and that's the extensor carpi radialis that goes to the thumb side right in here to this area and then we don't have a pronator we don't have a Palomar is there so on the back of the hand we've got an extensor digitorum so on the top of the forearm it's like the front we have to take the first layer off to get to that layer on the back of the extensor digitorum are ones that extend to digit so they straighten out the digits the flexors in the front bands of digits they're much stronger it's easier to hold things this way than this way have you know is that it's hard to carry things this way this way so I'm top we don't need as much muscle mass for that motion so the extensor digitorum is sort of a skinnier bone that's laying on top of it and that's right here right on top of it that goes into all the finger tendons when you start starting these tenders it's pretty profound they go all the tips of the fingers a little pretty I mean every little dish it has to have its own Mosul defense it's its own way it's pretty intensive so when I get to the model here basically we're looking at these muscles here on top now so let's go back to the brachioradialis and this is the last thing and then I'll let you sleep or study with well it's almost dark now I'm like I'm getting tired the brachioradialis was that thought going up and so that goes all the way up today pretty much to almost to be chaffed so then right next to that but this is important right next to that we got a couple of muscles number 20 and 21 their name I think at least my wall and those go to the thumb side those are the extensor carpi radialis there's all those in the brevets law means law brings me short I'm not differentiating that it's really the same muscle as far as we're concerned then on the outside right by the bone I have one that goes to the pinky that's the extensor carpi ulnaris right by the ball and then on top you can see here you've got a whole web of tenants that go through all the digits that's and you see the minimum common appeared over here that's extensor digitorum O's yes yeah yeah that's it right there wow that's a good one yeah no I mean these these muscles I mean you understand carpal tunnel when you look at all these type of muscles there's so much going on in these little forearms of ours and they just put me out as crazy their title like it's nothing it's just tight but the pronator teres well so when you type you have to always have to palm down at least in the classic guitar keyboards and so that muscle is always short and you've got us going through you've got the media nerve going through you and if that's always short it's going to fire up because it's always imitated and after a while it does not want to be here it ated and then it shoots and it's of course gives you carpal tunnel syndrome and so then we have to throw it down then you give you these things to hold in your braces yeah well see if the keyboard natural neutral you got to just be much neutral what's not mu Z this is like this so yeah but I don't know that's like really hard to figure out what's where with that but they do have keyboards that are a little bit curved and I think that I mean that is for bio knowledge because of that all right how is that doing get ready for some lap time all right let's do that
