all right engine in this video we're going to talk about the blood vessels around the head and the neck so we're going to go through piece by piece we're going to start with the arteries and then we're going to follow up afterwards with the veins all right so let's go ah aad and get started down here at the bottom all right so if you guys look here we're going to see this nice little vessel here 179 this guy right here is actually called the left common cored artery it actually comes right off the aortic Arch okay so it's the second to come off the aortic Arch because you know off the aortic Arch you have What's called the brachio calic artery that one will go into What's called the right subclavian and the right comared the second one is the left comic corate so this is this guy right here the left comic corate will move up up up superiorly and then it'll Branch into what's called an external and internal cored artery before I show you that let me angle the skull here a little bit so it can actually be a little easier to see all right so if we come up here you're going to get to this point here at 71 and it's actually going to split the vessel will split into two structures one is it's going to be called the external Cor artery which is 71 in the back here you can kind of see a tiny little guy here 72 that's the internal cored artery the internal Coro artery will continue to move upwards through the ktic canal and then the frame and Las serum and it'll go in actually into the brain and Supply The Circle of Willis okay we'll have another video on The Circle of Willis okay now the external corate artery is going to supply a lot of the actual external structures one of them is it gives off a branch here 73 73 is actually called The Superior thyroid artery okay okay so it's going to give off a superior thyroid artery then if we go up a little bit more we can see a tiny little vessel right here coming off of the external cor artery it's a tiny little one here and it actually goes underneath a lot of these muscles to supply the tongue via it's called the lingual artery okay so we have the superior thyroid artery then the next one is the lingual artery all right so if we follow this up more we're going to have here again this is the facial artery okay so it's going to come up over the mandible and it's going to be supplying a lot of the muscles of the face and some of the skin of the face okay so this is going to be the facial artery right there okay then if we come back here and take another little view okay we had external corate AR in order we had Superior thyroid we had lingal we had facial as we continue upwards you're going to give off another one that's going to go right here in the back okay so you know you have the mandibular Condes it's going to go right posterior to this posterior mular cond backwards this artery right there is called the maxillary artery okay so it's called the maxillary artery and then one more branch is going to be going back up here so this is going to be called The Superficial temp temporal artery so the superficial temporal artery so have maxillary artery superficial temporal artery and then one more is it comes from the back okay so again if you guys see this another another Branch coming off here this is another branch of the external corate arter it actually comes here kind of dips underneath the mastoid process here and comes out the back into the occipital region okay this is called the occipital artery okay so let's go do a quick recap of them running up through the top all the way through okay so recap left common cored gives off external cored artery and internal cored artery internal corate artery goes up and supplies a Circle of Willis that was 72 71 is the external corate artery what was the first Branch here Superior thyroid the next one is this tiny little guy here that moves underneath a lot of these muscles here these super Hy muscles this is called the lingual artery another Branch comes up over the mandible and this is the facial artery then as it proceeds superiorly it gives off another Branch going up right here you can kind of see it right here in the back part of the mandibular cile this postor mandibular cile here this right there is called the maxillary artery then as we go up even more superiorly up into the temple region where the temporalis muscle is you're going to have the superficial temporal artery and then if we come backwards we'll see a tiny little guy coming off here that goes underneath the mid process and into the back where the occipital region is this is the occipital artery all right so that covers the branches of the external corate artery all right so this is actually going to be another view of the facial artery here another view of the facial artery but as you continue to go upwards you'll see what's called another artery kind of coming out from the orbit here this is actually called the Supra trolear Ary it runs with What's called the super trolear nerve which is a branch off of the trigeminal nerve but again this artery here is actually called the Supra trolear artery okay just so you don't get it confused with the facial artery all right so let's hit one more artery down here in the lower part of the neck before we move up on the veins so if you remember I told you that the aortic Arch had three big vessels coming off of it one was called the brachio calic artery the brachio IC artery split into What's called the right subclavian and the right comared the next one was the left comara we already talked about that all of its branches the third branch is going to be right here this tiny little guy here 83 This is called the left subclavian artery okay so the left sub caving artery will then continue eventually into What's called the axillary artery okay so it'll also have some of its branches though too okay so that's the subclavian artery all right guys I just took the calvaria off or the skull cap and what we're going to see here is we're going to see a nice little blue Dural sinus now Dural sinuses are basically veins they're just enclosed within what's called a dural space and a dural space is basically whenever you have What's called the periostal layer of the duramater and the mininal layer from the duramater they break away usually they're very very closely connected but they break away and in between them they're going to have this Dural sinus which basically acts like a vein this Dural sinus right there is actually called The Superior s Al sinus and it actually runs within a nice little Dural SEPTA which we call the falx cerebri which is within the longitudinal fissure okay so again that's the F cerebrite it's one of the Dural sinuses it's acting like a vein and it's draining the blood okay and it's going to then take it to some other structures okay so again that's the superior sagittal sinus all right guys so now we're going to take a look at the Dural sinuses inside of the skull here a little bit on the inferior portion so we saw the superior sagittal sinus on the skull cap now we're look here in the inside if you look here we're going to have What's called the occipital sinus okay so this one right here is called the occipital sinus then we're going to have this nice little big old structure right here called The Junction or the Confluence of a lot of the sinuses okay so that's the junction of the Confluence of the sinuses and again this is the occipital moving here this sinus would just kind of moving from side to side here a little bit more interiorly this is called the transverse sinus transverse sinus then it actually is going to have a little sinus here that's moving on the upper part um of the petris component of the temporal bone so this is called this one up here is called the superior petal sinus and then there's one right here which is on the inferior part of the uh petus component of the temporal bone this is called the inferior petal sinus if you guys remember from the Abdus nerve video it moves with the Abdus nerve through dellos canal into the cavernous sinus so again this is the inferior petal sinus right there this right here is called the sigmoid sinus okay this is called the sigmoid sinus now eventually what happens is a lot of the blood from these Dural sinuses eventually drain into What's called the sigmoid sinus and the sigmoid sinus empties this blood into What's called the internal jugular vein which runs through a hole in the skull called the jugular foramen okay so it'll move through a hole in the skull called the jugular framan there's the jugular framan there it actually moves through that hole and again this blood from the sigmoid sinus dumps into the internal jugular vein the internal jugular vein will move through the jugular fan and eventually it'll take the blood downwards where it combines with another vein called the subclavian vein to form What's called the brachio spalc vein we'll talk about that quick recap here we go oxital sinus Junction of Confluence of the sinus transverse sinus Superior petal sinus inferior petal sinus sigmoid sinus sigmoid dumps into the internal jugular vein which goes down through the jugular fan combines with the subclavian vein to form What's called the brachio falic vein all right so let's look at that now in the anterior inferior portion of the neck all right so going to get look at these actual vessels that I told you the internal jugular the vein we got to come down into the anterior inferior neck so right here you can't see it but the internal jugg of the vein eventually comes down and it runs right here this is like the hole the Lumin of it this part right there so this is the internal jug of the vein but it's on the left side so this is the left internal jug of the vein this whole structure over here is the left subclavian vein remember what I told you the left subclavian vein and the left internal jugular vein Fus together or come together converge together to form this structure here 99 called the left brachio falic vein okay same thing on the other side now before we go over there you can see a tiny little nub here that little nub is where the external jugular vein dumps its blood into you it actually runs across the sternal clal mastoid so it's a little bit more superficial but again you can't see it very well uh right here we'll look on the other side you see you can see a little better all right so taking a look here you're going to see a little better this is actually the external jugular vein so you see how it's moving across the sternomastoid okay so this is draining a lot of structures from the external uh side right so from the face the actual back of the head and stuff like that so it's draining a lot of those structures so again this is the external jugular vein comes downward like we said and empties into this structure over here okay so since that's the right external jugular vein it dumps over here into the right subclavian vein and again if you can kind of see right here you'll see a tiny little tidbit of the right internal jugular vein fusing with the right subclavian vein to form the right brachio falic which eventually merges is with the left brachio calic to form What's called the superior vena which empties into the right atrium of the heart all right so that covers all of that all right nin so that pretty much covers everything that we were going to talk about with all the vessels of the head and the neck and even inside of the skull I hope all of it made sense I hope you guys really did enjoy it if you guys did please hit the like button comment down in the comment section and please subscribe as always Ninja
