all right engineers in this video we're going to talk about the thoracic abdominal circulation okay so what we're going to try to do in this video is we're going to go through you know taking here the diaphragm separating the thoracic aorta from the abdominal aorta we have a blank diagram like this set up on our Instagram page so if you guys go on our Instagram page you guys can actually have this as the template to kind of follow with me as I go through this okay also you guys just want to pause the video you know and take some time to draw this all out you know you guys can and then come back and we can actually go through this together alright so we're going to start up here first with the thoracic aorta okay so let's say we start here first with a thoracic cord and you can tell that because the thoracic aorta is the large vessel that's going to be above or superior to the diaphragm this green line here supposed to represent the diaphragm so superior to the actual diaphragm is going to be this large artery here called the thoracic aorta it's a part of the descending aorta which is coming off they Orta karch okay so this is called our thoracic aorta alright now often thoracic aorta is many many different types of vessels that come off of it okay so for example the first one to come off of this we could say there's a many many of them let's say we go with this one there's actually a vessel that comes off they order and it goes some supplies in between the ribs so when it goes in between the ribs it's actually called an intercostal artery and it's on the posterior side so it's actually called the posterior intercostal artery okay and you have many of these so the posterior costal arteries going to be those arteries that are running in between the ribs so they're supplying the external internal intercostals okay also we have a vessel that actually can give a branch right here to the actual diaphragm so you know this is actually going to give an actual branch right here to the diaphragm and supply the actual muscles there so this would actually be called the it's a phrenic artery so it supplies that the actual diaphragm but it's above the diaphragm so we call it the superior phrenic okay so this is called the superior phrenic artery okay so there's our superior phrenic then if we come over here we have other branches that are going to different parts okay so let's see as we talk we do it with this first one up here and okay this is for the bronchial bronchial arteries okay so this is the bronchial artery so this is going to go and supply the bronchi so it's going to supply the bronchi can provide oxygen-rich blood to the many of the different cells within the bronchi most of these are going to be pretty simple because if you think about it tells you what it's serving so it's not super complicated to understand that right okay so next one let's say that we go a little bit you know near that we have the esophagus so we have the esophageal artery okay so then we have the esophageal artery you already know what it does it supplies the esophagus so simple stuff here and then we could have another one you know there's an actual cavity located with inside your actual thoracic cavity it's called the mediastinum houses you know the actual heart and you also have our going to have other structures in that area like the thymus gland you can even have the esophagus a lot of different types of lymphatic structures within the area there's going to be an artery that supplies that and that's called the mediastinal artery so the media style artery so it's going to supply mainly the main structures that it does supply is it supplies the actual lymphatic structures within an area like the lymph glands so the thymus gland as well as some of the areolar connective tissue within the posterior aspect of the mediastinum okay so that's our mediastinal artery then you also know that there's actually a fibrous tissue that's surrounding the actual heart and it's called the fibrous pericardium the pericardium has to get his blood supply to so you know there's also what's called the pericardial artery right so the pericardial artery so that's a pericardial artery and again that's going to supply the actual dense fibrous irregular connective tissue like the fibrous pericardium now here's the thing so thoracic aorta if you're actually looking inside of the actual thoracic cavity you guys obviously you guys watch the anatomy video a little bit of orientation for you you know if you look at a thoracic your T obviously note system thoracic cavity if you imagine you have your vertebral column that's going to be right behind it so posterior to be at the actual thoracic aorta is going to be the part of the vertebral column also it's going to be very very be close so to the left of it you're going to have the left plural of the lung okay also right behind it also besides the vertebral column is what's called the Hemi azygos vein we'll talk about that when we look at more vessels within thoracic cavity okay now on the actual left of it you're going to have other structures so we said there's going to be the left pleura okay also you're going to have on the right of you're gonna have thoracic duct in case you have the thoracic duct you'll be as I guess vein there's a lot of different structures they're going to be near by the thoracic aorta okay so that's the thoracic aorta vessel so again we covered the bronchial really comfy esophageal artery you cover the mediastinal artery the pericardial artery the posterior intercostal arteries and again that will be a left and a right and then the superior friend of Carter which again will be a left and right once the thoracic aorta pierces through the actual diaphragm it comes out as a different type of you know part of this aorta it's still descending it's still going down but now it's located within the abdominal cavity so now it's called the abdominal aorta guess this is called your abdominal and your Oregon now abdominal aorta is very cool because as you can see there is a boatload of branches that are coming off of this bad boy so let's go ahead and go through some of the easy ones first and then we'll go over to one to have more branches all right so first thing you know there's a superior phrenic artery supply on the top of the diaphragm there's one that's supplying the inferior part of the diaphragm right below it so this guy can actually supply the inferior aspect of the diaphragm so it's called E in fear your friend Carter II okay so this is called your inferior phrenic artery all right then got a little hints for you guys if you guys look here this is actually going to be what your adrenal gland so your adrenal gland is actually gonna have a blood supply now you can actually name it two different types of names okay so you can call it the adrenal artery and again you have two adrenal glands so on one on the right side one on the left side so you can't have a right and a left adrenal artery or you can call it a right and a left supra renal artery since it's above the kidneys it's up to you guys I'm just going to write adrenal cuz it's plus two right alright so right and the left adrenal artery okay same thing with the inferior frantic ardor there's going to be a right and left hand for your friend of artery okay now you have the kidneys right inferior to the actual adrenal glands or the suprarenal glands is going to be your actual kidneys so these are you're not gonna call them kidney arteries oh he called the renal artery okay so specifically you have a right and left renal artery so you're going to have a right and a left renal artery all right then you can obviously tell that this is going to be representing the male gonads you know so that's going to be the testes and this is actually going to be for the actual female gonads or the ovaries right so this is going to be good nate'll arteries simple as that but if it's in a male you would call the testicular arteries if it's in a female you call the ovarian arteries simple as that okay but we're just going to call it in this case we're going to call the gonadal arteries so go nate'll arteries okay and again it would be a right and left then you're going to have other ones that are still going on with the lower part of the actual abdomen so as you get lower you know you have what's called the cervical vertebrae then you have the thoracic part then you have the lumbar part you have arteries that are specifically coming off the lower part of the abdominal aorta going to supply the lumbar region so some of the muscles in the lumbar region okay so this is going to be the lumbar artery okay since our lumbar artery alright and again you have right and left there all right now as we keep going forward let's say that we get down as we go down the abdominal aorta to begin to split so there's a branching point of it so as you get ready to split there's a big big branch let's say that we have just to be consistent let's say that this is going to be the left side and this will be the right one so for example this will be the left common iliac so I'm gonna put left common iliac artery then less common iliac artery can branch okay so he can branch into an external branch in an internal branch if it goes to the external branch we'll cover that one in another video so I'm going to write down here specifically the left external iliac artery but we're not going to talk about his branches in this video we will in another video when we talk about blood flow through the actual lower limbs okay specifically we're going to try to focus on within the thoracic region the abdominal region some of the pelvic region alright the other branch of the common iliac arteries not just the external but there's also the internal so this will be the left internal iliac artery okay and this one has many branches okay so you know you've got the booty you got the superior gluteal muscles right so that the suitable artery so you have it's called a superior gluteal artery now the superior gluteal artery supplies a couple different structures so it mainly supplies the actual gluteus maximus okay it can supply another muscle underneath that which is called the gluteus medius and the gluteus minimus I'll write that down here on the side so this can supply the actual gluteus maximus it can supply the gluteus medius and minimus okay so those are some of the muscles that this actual artery can supply alright then you have one that's going to be a little bit infinite below that so it's an inferior so it's the inferior gluteal artery the inferior gluteal artery now the inferior gluteal artery similar it does supply the gluteus maximus but it also supplies the other different branch you know she actually underneath the gluteus maximus there's a little these muscles called you have up it's called the piriformis muscle and you also have another one called the quadratus femoris not the quadriceps the quadratus for Morris so this is going to supply that structure so the inferior gluteal artery is going to be specifically supply the gluteus maximus but not as much as the superior gluteal it's going to supply the piriformis and it's also like we said going to supply the quadratus from worse the quadratus femoris all right you then have another one it's called the internal pudendal artery okay so yeah what's called the internal good dental artery okay now the internal pudendal artery specifically going to be supplying the external genitalia okay so for males it actually supplies the actual penis specifically within the penile arterioles for the erection and it also can supply some of the actual external genitalia for the female maybe the clitoris as well so it supplies the external genitalia as well as the perineum which the space between your anus and your actual specifically the gonads but for the male you would say it's the actual space in between the actual testicles right and the anus whereas the female it would be also the space between the actual vaginal canal and then also between the anus okay so it's going to supply those structures so again it's going to supply the external genitalia as well as the perineum okay then you have the last one and this is going to be the operator artery okay so the last one is going to be the obturator artery here in the obturator artery is a cool one because it supplies mainly the what's called the medial compartment of the thigh okay so it supplies the medial compartment of the thigh the medial compartment of the thigh so a lot of different muscles that this guy can supply so if you think about he could supply some of the actual adductor muscles okay somebody had doctor muscles alrighty so we got that let's do a quick review on this side and we'll go keep going over here so again we got off the abdominal aorta get the inferior frantic artery which supplies the actual inferior portion of the diaphragm you have the right and left adrenal artery which goes to the adrenal gland you have the right left renal artery which is going to the kidneys you have the kanata arteries which is going to the actual testes in the male's and the ovaries within the female so again you could call it the actual testicular artery or if you call the ovarian arteries yet the Lombard which is supplying some of the muscles in the lumbar region okay many different muscles in that area then you have a branches you have these branches coming off the abdominal aorta I got a little left common iliac and the right common iliac if we follow this for a second though the less common iliac can branch into the left external which we'll have another video on and discuss all the vessels that continues on as like the femoral and so on and so forth and then the other is the internal iliac right and that gives weight to the superior gluteal artery which supply to the gluteus maximus the gluteus medius and gluteus minimus the inferior gluteal artery which supplies the gluteus maximus the piriformis and the quadratus femoris the internal pudendal which supplies a lot of the external genitalia and the perineum and then you have the opto rear area which is supplying the medial compartment of the thigh okay so some of the adductor muscles okay so to continue on I told you here that imagine here is the abdominal aorta it branches when it branches it gives off a left common iliac and a right common iliac but you guys already know what this is going to be so right common iliac artery and the right common iliac eight branches so it's going to get away to a external iliac and an internal X is going to be right so again in this case it's going to be right external iliac artery and this is going to be the left external iliac artery sweet deal okay so let's come back up to this top point and we'll go back towards the middle okay so it's going to be a lot of branches here so just hang in there with me okay so off the abdominal aorta you have this huge trunk okay a trunk coming off of the abdominal aorta it is called the celiac trunk so they called the celiac trunk or the celiac artery we're going to call it here the celiac trunk according to the literature that we're following right so the celiac trunk now off of the celiac trunk there's going to be three branches that are coming off of this okay so the easy one is it's actually one it's going to come right off of it it's the left gastric artery so you can imagine what the left gastric artery is gonna supply it's going to supply the stomach there's the left gastric artery okay now that's one main branch office iliac trunk the second branch is the splenic artery and you know that the spleen is normally going to the left side honest you have situs inversus totalis right which is actually with switch and in that case the spleen would be on the right but we're not talking about that we're talking about normal individuals so yeah in this case you're going to have the splenic artery going to the left side so we're only going to say left because there's only a spleen on the left side this is the splenic artery okay now the splenic artery has different branches we're not going to go into tons of them we're just going to talk about one of the main ones off of the splenic artery since it's going to the left side our stomach has imagined here is our stomach for a second and here's our stomach we'll talk about this more in the GI Anatomy but you have what's called the greater curvature of the stomach hanging off of the greater curvature is this actual what's called a Mezen Terry but they call it an omentum it's called the greater omentum okay now what happens is this splenic artery gives off a branch that goes and supplies the actual omentum the greater omentum as well as some of the actual stomach so that is called the left gastroepiploic sometimes they call it the gastro mental arteries too but we're going to call here the gastroepiploic so specifically this is the left gastro epi pulic artery I'm surprised I even spelled that right all right so laughs left gastroepiploic artery all right now I got the splenic artery giving way to the left gastroepiploic artery and again what is it supplying just so we remember when you hear this word gastroepiploic you can also remember gastro omental meaning it supplies the stomach as well as the greater omentum which is a mesentery okay mesentery is just a double-layered epithelial membrane okay a double-layered epithelial membranes where a lot of blood vessels lymphatic fibers nerves run through okay now we go into this big old beast all right so we got the left gastric splenic artery now we got this next one this next one is called the common hepatic artery okay so this is called the common hepatic artery now if you noticed usually in every time you hear the word common it's going to be splitting okay so you're going to be branching out into different parts and that's what this one does so one of the branches here off the common a patek artery let's go to this way here first this is actually going to be called the hepatic artery proper so obviously you know that this is going to be the paddock artery proper now and again some people were like oh is that the right or the left hepatic artery proper is just to saying that it's actually going to deliver and normally in normal individuals the liver is usually always on the right side so we don't have to say right a patek artery property we just say a patek artery proper because there's no liver on the left side all right so you call this one the hepatic artery proper why they put artery before the proper no idea you can probably call it a paddock proper artery you know it doesn't matter just as long as you got that point there all right the Apothecary proper then gives off a couple different branches so one of the branches is going to go to the right lobe of the liver okay so if it goes to the right little deliberate it's the right hepatic artery so one is going to be the right hepatic artery and then eventually what happens we'll talk about this more in the GI physiology but specifically this is going to go to what's called a liver lobule where you're going to actually undergo specific types of it's going provide oxygen and nutrients and different types of substances to the apat asite the liver cells within the actual liver I'm sorry within the liver lobule all right now you have another one which is going to the left lobe of the liver okay so you have the right lobe of the liver left lobe of liver this is going to be the left to patek artery so this is called the left hepatic artery all right sweet deal now another thing so we had a left gastric artery coming off of the celiac trunk now since the liver is on the right side it provides the branch that can go over and supply other parts of the actual stomach so you know over here we said that specifically you had the get the gastroepiploic artery which is supplying branches here to the omentum and even maybe the greater curvature of the stomach then you're going to have the left gastric artery which might be supplying this fundus part here the right gastric artery is mainly going to be supplying the pylorus okay so it's going to be supplying a lot of the pylorus region there it may be even parts of the body okay so specifically this one is going to be the right gastric artery so right gastric artery and again the right gastric artery is also going to be supplying the stomach more along the lines of the pylorus and even the parts what's called just the body of the stomach okay then common a patek artery not only gives off this branch but it also gives off another branch this other branch here is called the gastro duodenal artery okay so all for this one we're going to have another one which is going to be called the astro the water artery let's write this one down here it's called the gastro duodenal artery okay so gastro the walnut artery now the gastric due on water you can obviously recognize what this is going to be supplying so imagine here's my stomach okay and you're going to have what's called this fundus region the body region the pylorus and then you have the first foot of the small intestine this artery this gastro the Wadden artery is mainly supplying the pylorus the end part of the stomach and the first part of the small intestine which is called the duodenum okay so that's what the gastro duodenum artery supplying it's mainly supplying the pylorus of the stomach as well as the first fluid small intestine which is called the duodenal okay the duodenum so it's about the gash of the one artery now the gastro dogged one artery can split okay and it can supply other reasons also so off of this one it's going to give a branch this is going to go okay now if you imagine here say I draw another part here let's say I have here for a second have the stomach the duodenum there and again you have this omentum here right but you also have a lesser curvature with some momentum over there - this is where the right gastroepiploic artery comes in so the right gastropub lorg artery is going to supply some of this actual lesser omentum okay so that's going to be this branch here so this branch right here coming off of the gastropod no artery is specifically going to be the right gastro happy Loic artery okay so mainly supplying some of the actual again it supplies the stomach it does supply the stomach region but it's also going to be supplying some of that actual lesser omentum which is a mesentery coming from the lesser curvature and anchoring it to what's called the liver okay then we have another branch another branch here is going to do is called the superior pancreatic duodenum artery okay so this one right here is called the superior pancreatic duodenal artery okay that's a big old beast so the superior pancreatic duodenal artery okay so now the superior pancreatic duodenal so let's stay here just for a second here so they understand orientation let's say here's the stomach okay and then you're going to have again that first foot of small test which is your duodenum right around that area you're going to have the pancreas okay you probably saw this in the model that we had right so here's the pancreas just this is obviously a quick crude diagram but what happens is coming off the gastric the Wadden artery the gastro is the wall arteries going to give out this branch ring everyone's going to be the gastropod pulic artery which is going to be supplying this actual again what is this momentum here lesser omentum then it's also going to apply some of the stomach but it's also going to go another branch so it gives off one branch which is going to come over here and supply what supplies the pancreas some branches to the pancreas as well as are going to supply parts of the duodenum okay so that's the superior pancreatic duodenal artery so again what is it supply you can have this to eat within its name it's supplying the actual superior aspect of the pancreas as well as the beginning parts of the duodenum that's it okay now we come over here to another branch so we covered these big big branches now we're going to go to some of the other you know slightly a little bit more you know difficult branches okay coming off the abdominal aorta so if we kind of go in order we went celiac trunk right after the celiac trunk is going to come this next big vessel which is called the superior mesenteric artery okay so if we're going down so again you got celiac trunk which are sure to be down here in the actual Dominic I'm sorry if we go here we have the celiac trunk right beneath that is going to be the superior mesenteric and then right beneath that is the inferior mesenteric okay we're going to talk about this one here so this is the superior mesenteric this one will be the inferior mesenteric so the superior mesenteric artery okay so the superior mesenteric artery is going to be doing what it's going to give off many many many branches it supplies most of our intestines okay so one of the big ones that supplies the actual small intestines so supply that through what's called the intestinal arteries so the intestinal arteries are going to be going and supplying what's called the Jew genome in the ileum now the Jew genome and the ileum is a little bit different so if we actually for a second here let's say we take for a second here we go through just real quickly the parts of the actual small intestine so a small intestine has three different parts okay first part is the duodenum the next part is the Jew genome and the next part is the ileum the intestinal arteries here which are coming off of the superior mesenteric artery are mainly going to supply more of the Jews demand ileum but it does supply a little bit of the duodenum okay so again the actual intestinal arteries are going to be going and supplying the Jews amilia mainly mainly these two guys here okay but just a little bit of this one a little bit of the duodenum all right so that's the intestinal arteries then if we keep going get if we actually go to a different part now so now we go into this next part we have another part of our actual intestine so now let me make another quick diagram let's stay here for a second I have I have my my appendix then I have what's called the cecum which is attaching to the appendix and then I go up I have the eighth ending : I got the transverse colon I go descending colon here I go s-shaped sigmoid colon and then I go into the rectum and I go anal canal okay specifically this superior mesenteric artery is supplying a lot it's applying this part here with the actual cecum right here and it's also going to supply a little bit of the actual ileum okay the small intestine part of it and it's going to supply a little bit of the appendix this one right there that part right there is called the ileal like artery okay so we're going to call this one the ilio Kolok ilio Kolok artery okay so that's the iliac Olek is going to supply some of the cecum it's going to supply a little bit of the appendix and it D be going to supply a part of the ileum which is actually the last part of the small intestine the next one is going to supply this ascending colon okay so now you're going to have this part here a branch that's actually going to be supplying a lot of the ascending colon so if it's supplying a lot of the ascending colon this specific branch here is actually going to be the it's on the right side so it's called the right Kolak artery okay it's just the right call mainly supplying the ascending colon so this is called the right Kolak artery then we have another part and that's going to be this part here the transverse colon so supplying the actual transverse colon here is going to be this branch here and this branch here is going to be specifically coming from the middle Kolak artery okay so it's the middle Howlett okay this is the middle Kolak so it supplies the actual transverse colon as well as the way what's called the transverse needs a colon okay so again one more time superior mesenteric supplies the intestinal arteries which gives way to the vessels of you know supplies the duodenum the jujin um the ileum a little bit less on the duodenum ileal Kolok which is applying the actual cecum the ileum which is the last part of small intestine and the appendix the right cold look which is applying the ascending colon the middle colic which is supplying the actual transverse colon on what's called the transverse musical which is like a mesentery okay good there then we go into the next part okay now we go into what's called the inferior mesenteric artery which is again lower okay lower down so now we go to this one inferior mez enteric artery okay inferior mesenteric artery is a cool one too so he's going to supply other parts so let's actually have this let's come back to this intestinal drawing we have over here so if we come back over here we said we had the descending colon sigmoid colon which is a shape and we have the rectum so if we look here let's say we do this one in a different color now there's branches that are going to supply the descending colon and it's not that bad if you think about it descending colon normally should be on the left side so what should this one be left Kulik okay so this one should be left colon right there over in a second then we have another branch here and that's applying the sigmoid colon waiting now is going to be sigmoid largely and we'll write that over in a second okay and then we have another one over there which is going to be supplying the rectum so if you have this branch here which is going to be supplying the rectum here this is actually going to be called the superior rectal artery which gives way to a mid and inferior rectal artery okay and we'll write that down over there so again really quick left cold is supplying descending colon sigmoid artery supplying the sigmoid colon superior regular tribe providing the actual rectum and it gives branches to the mid and inferior rect arteries all right so let's write those over here and we'll just recap them as we're writing so again enter your mesenteric artery gives way to the left Kolok Ardrey gives way to the sigmoid alar tree and it gives way to the superior rectal artery okay and the superior rectory gives off the two branches one is the mid part of it so the mid rectal artery and the other one is actually going to be the inferior rectal artery all right we did a great job guys all right I hope all of this made sense so far now I want to cover one more thing one more kind of relevant tip here since we're talking about the aorta there is a condition we probably talked about in other videos too with the tunic layers there's a disease that is actually very very very very dangerous because it can affect this whole a order primarily the entire descending order that condition is called Marfan syndrome okay it's called Marfan syndrome and Marfan syndrome is an autosomal dominant disorder it's an autosomal dominant disorder and it's usually due to the mutation okay in a gene that produces fibrin so it's a mutation mutation and what's called the fibrin gene the fibrin gene is important because fibrin is a very important elastic connective tissue so it's a mutation in fibrin gene and what happens this fibrin is very important within the elastic connective tissue so it controls the actual the ability for the aorta what's what is elasticity whether by definition elasticity is not what most people think they think it just all you can stretch it now elastic means it can stretch but it can recoil so more specifically wants to resist any changes in the deformation of a structure so if you're actually lacking this fibrin gene what happens to the elasticity of these vessels it decreases there's a decrease in the elasticity of vessels they can't take on as much pressure as they could normally and what happens is due to this situation the actual blood dissects in between certain layers of the actual aorta specifically thoracic and abdominal we're common within the abdominal in this situation if it happened this can cause what's called an aortic dissection a ordered dissection and what's really bounded by ordered dissections is that if it happens sometimes this can actually rupture and if they rupture that's very very dangerous another thing that can happen besides the dissection is they can actually dilate they can become very very dilated region so it can cause a or t'k and your isms and if this eventually this can again lead to rupturing and this is one of the big big dangers of Marfan syndrome because of that ruptures oh my goodness there's going to be a lot of blood that's going to be lost in you're going to go into hypovolemic shock and this person is not going to last very long if that happens so another thing well since we're here talking about Marfan syndrome not only does it decrease the elasticity of these vessels febrile and is not just important within blood vessels it's important a lot of different structures it's also important in our heart valves so you know in certain individuals who are actually having this mutation the fibrin gene they have very very increased incidences of what's called mitral valve prolapse ah's so their valves actually blow back into the atria okay and the clay actually can cause regurgitation issues so in this situation not only they have increased incidence of aortic dissections and they order aneurysms but they have increased incidence of mitral valve prolapse okay and this is very very dangerous because over time this can cause a lot of problems and it might have to be repaired usually with Marfan syndrome the more dangerous effect is on the cardiovascular system but it also does affect other systems if you notice anybody who has more fun syndrome their fingers are wrecking a long they got long long fingers really really spin they're very tall very very tall individuals in a very slender okay not just that they can actually do a test usually usually if they do the test they take their actual thumb we use this thumb because this thumb is all nasty if I take this thumb here usually they close their hand and their thumb pops out of the side that's one of the things that they actually see in Marfan syndrome so they have very very long fingers okay also since they're not having this fibula they don't have as much you know again what is elasticity wants to resist change in d-formation what happens these individuals they actually have hyper reflexive and they have a lot of they can stretch their skin out okay so they can stretch their skin out a lot and their actual joints are very very hyper flexible another thing is because it's affecting connective tissues and other thing that you'll see within Marfan syndrome is in the eyes their lens there's these things called these Xillia ciliary zonals or suspensory ligaments whenever they're last this actual of fibrin is deficient or mutated it can't hold on to the lens and the limp dislocates so it can also cause lens dislocation lens dislocation and usually it's a partial so they called a subluxation of the lens but it's a lens dislocation and since we're doing that again we said they could have you know very tall okay and also we said slender long fingers and they're also very very flexible highly flexible so we'll say very very flexible another thing that can also affect one of the early really dangerous ones if it happens this usually happens a lot of the patients large amount of the patients I think about 90% of the patients usually develop this it's called dura lacked Asia it's a very unfortunate condition they're elect Asia and dura lacked Asia is you have what's called a dural sac around the lumbar and sacral region of the spinal cord that surrounds it and usually do this in the situation because of their they're actually have changes a lot of the skeletal system usually have scoliosis Sina can remember scoliosis well if I draw like a little individual here over here we can say let's say here I have a guy here and here he is he's looking at you and he's smiling right okay here's this guy if you look in the back of them so let's say we look at a spine his spine is actually going to look like this okay so this is this guy here okay and if you kind of remember that by this s like shape structure that scoliosis so they have increased chances of developing scoliosis and while we're mentioning that also you can see their chest is caved in they have a caved in chest and whenever they have that caved in chest it's called pectus excavatum okay pectus excavatum alright so again with Marfan syndrome a lot of these things can happen also if you want to we can add in one last thing in here it's not as common but their lungs they can actually have what's called a spontaneous pneumothorax okay so they can develop a situation in which they can actually have pneumothorax air which is located
