Vertebrae Anatomy of Spinal Cord

Vertebrae Anatomy of Spinal Cord Lesson |

Today we'll be looking at the actual skeleton, vertebral spinal cord anatomy so the accessibility nice was hard on her screen and the screen vertebral spinal cord anatomy and it consists of skull to hide bone vertical column ribcage and sternum vertebral spinal cord anatomy so a few key points of our the actual skeleton is that the vertebral spinal cord anatomy axial skeleton and spinal cord. Our bones that form Center axes body the vertebral spinal cord anatomy appendicular skeleton on the other half odd see clay said joins laughs vertebral spinal cord anatomy I know we joined says they allow for a range of movements vertebral spinal cord anatomy which involve the upper limb blowing and stuff the only exception for the vertebral spinal cord anatomy actual item in the mandible because it's the jaw and it you know it moves vertebral spinal cord anatomy a lot but today's lesson we're going to focus on the vertical vertebrae anatomy problems.

You know the vertical column has vertebral spinal cord anatomy the cervical c1 c7 there's a thoracic region which has 12 verse frozen at lumbar vertebral spinal cord anatomy which has 5 vertebras sacral which is basically one but his five bones vertebral spinal cord anatomy  fuse fuse together as one and a kick suit Coptics jaw which is a tail bone vertebral spinal cord anatomy which is four bones fuse together as one as well so the learning objective is vertebral spinal cord anatomy to be comparing the different types of vertebrates also see the latin vertebral spinal cord anatomy names parts and surfaces.

You know origins entitlements of muscles and vertebral spinal cord anatomy ligaments to these surfaces and the difference between the cervical vertebral spinal cord anatomy thoracic and lumbar mainly so on the screen now you just have the vertical column so on the screen vertebral spinal cord anatomy now you can see the atlas the atlas is basically the first vertebral spinal cord anatomy cervical vertebra this is like a thin ring shaped vertebral spinal cord anatomy bone has no body or spanish process and i will go into a bit more vertebral spinal cord anatomy detail so the cervical you know it goes from c1 all the way vertebral spinal cord anatomy down to c7 and c7 is much highlighted now then you have thoracic vertebral spinal cord anatomy which starts off in the for actual region t1 all the way down to t12 and vertebral spinal cord anatomy the job of this is basically it provides the spinal canal for the spinal cord 1 as well as articulation with the ribs and we also have the oxygen region which is the vertebral spinal cord anatomy tailbone and as a final segment of the human.

Vegetable column and the sacrum is just superior vertebral spinal cord anatomy to it and the sacrum forms a posterior wall of the pelvic region and it's vertebral spinal cord anatomy triangle in shape begins you know slightly see it and you have the vertebral spinal cord anatomy lumbar which is like the most important part because most people when they vertebral spinal cord anatomy have you know sciatic or some sort of prolapsed disc or something is vertebral spinal cord anatomy usually in the lumbar region so here's a lateral view so you got the vertebral spinal cord anatomy atlas you are the access you've got all the others cervical thoracic lumbar vertebral spinal cord anatomy  sacral and coccygeal and during this lesson we're gonna basically vertebral spinal cord anatomy go into detail with each of them how they look the shapes and the vertebral spinal cord anatomy funny thing is you would expect also awful to be the same and the thoracic vertebral spinal cord anatomy  is the same on the lumbar to be the same but in fact they're all individually vertebral spinal cord anatomy different and some of the cervical itself like c1 c2 are different to c3 c5 c6 and so vertebral spinal cord anatomy on and you know so we're going to be looking into detail all the different parts and so we're gonna start with an anterior view of the first one the first vertebral spinal cord anatomy cervical vertebra C or Nautilus.

Vertebrae Anatomy of Spinal Cord Lesson

You can see the anterior arch the transverse process vertebral spinal cord anatomy and to your tubercle transverse foramen and a lateral mass so no vertebral spinal cord anatomy  it doesn't really make sense, so the latin terminology for those of you vertebral spinal cord anatomy that's interested is highlighted in the brackets so the English is on top and vertebral spinal cord anatomy so you can see posterior tubercle will be known as tubercle and post arias vertebral spinal cord anatomy in right in the posterior arch Marcus posterior you've got the superior vertebral spinal cord anatomy articular surface which is this is what buying City articulates with the vertebral spinal cord anatomy occipital condyles as well as the yeah the Oxford to Hondo and you have vertebral spinal cord anatomy  the transverse forces which has you know place where muscles and vertebral spinal cord anatomy ligaments could attach as well as I has a transverse vertebral spinal cord anatomy frame and through which the vertebral arteries as well as veins and nerves vertebral spinal cord anatomy run through and you are the anterior arch at the back so there's basically a vertebral spinal cord anatomy superior view so just to get the idea of we'll start with cervical vertebral spinal cord anatomy see why not listen a bit detail so if you were to highlight the vertebral spinal cord anatomy occipital bone so you can see the articulations that c1 the Atlas vertebral spinal cord anatomy  has sorry articulates obviously with the c2 axes on the bottom and the occipital bone on the top so when you assemble them together this is how they come along vertebral spinal cord anatomy and attach the articulation point.

So you see the fovea dentists of the c2 axis attaching vertebral spinal cord anatomy to the dentist's faces of the c1 atlas so now we're gonna go in really detail up vertebral spinal cord anatomy with the cervical vertebrae so it's basically ring shape and it has nobody
 so the key features always has nobody knows Phineas process vertebral spinal cord anatomy articulates with Oxford 20 to access the virtual frame and is circular in shape circular member and this transverse foramen allows passage of veins and vertebral spinal cord anatomy arteries and funny thing is this is the only transverse foramen which is actually put to use in compared to all the others so there's a picture of you know just showing vertebral spinal cord anatomy the arteries and veins and the nerve going through the foramen vertebral spinal cord anatomy so now we've got parts and surfaces of it let's start with pots we vertebral spinal cord anatomy have an anterior arch the anterior joins with a posterior arch you know to make a circle and and the posterior side of it you have the dense axis you also have the vertebral spinal cord anatomy posterior arch you have a posture tubercle to which the rectus vertebral spinal cord anatomy capitis minor which is a back muscle attaches to you.

You have the muscles of the neck involved in the vertebral spinal cord anatomy rotation of the head so I shown here attached to the transverse process you also vertebral spinal cord anatomy have a superior articular surface to which the occipital condyles attached vertebral spinal cord anatomy and the fovea dentist is found on the posterior side of the anterior to vertebral spinal cord anatomy Baku oral anterior arch Chasse and the transverse foramen is the apertures vertebral spinal cord anatomy found on the side only see one.

Transformer inlays passage for weighing in on trees near the vertebral spinal cord anatomy transverse foramen which is large and triangular in shape so that's one thing you vertebral spinal cord anatomy wanna note down the different surfaces all you have the vertebral spinal cord anatomy anterior to Baku to which the longest coleye muscle as vertebral spinal cord anatomy well as the ligaments attach when he's found of anterior posterior anterior vertebral spinal cord anatomy side and this is the groove or sulcus arterial or sokka's nerve I groove vertebral spinal cord anatomy through which you know when the arteries and veins vertebral spinal cord anatomy come up with the frame and they go on top of this and they pass on into vertebral spinal cord anatomy the foramen magnum so now let's start over the sea to access parts vertebral spinal cord anatomy  and surfaces so well the as a body unlike dc1 and the arrows has is vertebral spinal cord anatomy strong and cervical virtually allows for pivotal movement of the neck vertebral spinal cord anatomy allows for attachment of muscles and ligaments on transverse vertebral spinal cord anatomy process and as a bifid spinies person.

So it does have a spinach process but it's by fit so there's vertebral spinal cord anatomy two ends like like a cross so again we're gonna go in with the parts of the c2 axis you all the dense part which is the most important because this articulates with the atlas the c1 vertebral spinal cord anatomy above okay and you have the inferior articular whose process so this is vertebral spinal cord anatomy where the contains the fire set for the inferior side the lamina is where the vertebral spinal cord anatomy ligaments and flavor touches so here's just a small altercation of ligament in flavor and you have the different section so the pedicle is over here the pedicle is one of the two short stalks and you also have the experience process is important because it's Phineas process that is a place where the nuchal ligament attaches as well as the muscles of the neck so you know spinach process is very important please do make sure you pause the video and you know learn these stuff because I am going it very very very fast rate because you know have to get through all of it in less than 20 minutes that's the aim so you know the transverse process and it's next to the transverse process is where muscles and ligaments attach you then also have the muscles and ligaments attach the transverse process so then you have the dense phobia or dense axis.

You know the superior articular facet which attaches to the Atlas inferior which attaches to the c3 below it as I go for physio joint so remember that so the joint between two vitro's are known si
 Felicio join and you got a transverse foramen the trans miss but who arteries and veins but I'm not entirely sure it depends on your body structure but in most books it says that it doesn't go through that any other vertebral foramen as well which is an aperture formed by the union of the vertebral body and the vertebral arch and this is the area through which the spinal cord runs through so this is pretty much the main bit now the c2 to c7 have a body c1 does not have a body c3 to c6 the body looks the same but C 2 and C 7 have a different body.

Now the surfaces you have an apex of the denser this is a bit where it connects the ligament the inferior intervertebral surface you know the discs come together so you have a notch
 services are not Lamport as long as you know the parts it's the vertebral arch is obviously formed by the lamina and the pedicle so now let's look at the thoracic vertebra parts and surfaces so on screen you can clearly see that the Rasik vertebra is not just involved in you know giving space for the spinal cord running but it also has articulation with the ribs and the ribcage obviously protects your thoracic region your lungs your heart and everything like that so but the rascal attic where there's 12 of them t1 all the way down to 12 they have a heart shaped body and the body is much bigger than the cervical body the.

The bodies dose lead deeper compared to ventral so it's you know more like bend it in the front and rather than towards the back and the framing is smaller and circular so the different parts we're gonna start off with the lamina you've got the pedicle I'm not gonna go through these because you went through them previously you've got the spinous process remember to see one atlas does not have a spinous process to see two as a bifid cc7 has a longer spinous process and this one has a blue spine suppose which is long and sloping downwards that's the key information then you have the body is a heart shape very flat superior inferior surface seeking you can see how the vertebra of the thoracic region defers to the cervical region and you obviously don't have a transverse foramen.

Instead you just have a transverse process which contains transverse costal face set where the ribs attach okay so you don't have a frame and instead you have a costal facet or Freesat now there's other superior costal facets as well as inferior demi costal facets this is another region where the ribs attach and be the please do post video and read what's on the screen because I can't go in very detailed in the time limit I do you have so the difference is in thoracic vertebra or the th one looks more similar to the cervical vertebra whereas a lumbar one is what's on the screen now so please again pause the video and do check it do you got the inferior articular facet you got the virtual foramen which is smaller and circular but not triangle.

Vertebrae: How to Differentiate them :-

 This time so that's one of key information you want to take on board its next we're gonna be looking at the lumbar region so there's five of them they're kidney shaped police then transverse process so they don't have any no for foramen the spinous process large short and square and the size of the body increases from top to bottom.

Okay so we're gonna go through the different parts of the lumbar region as well so hopefully I know that I'm talking really fast through the videos and you know you don't gain a chance but do pause videos and read or sunscreen on the left as well as what comes up on the screen so the vertebral body it's also known as a centrum or the corpus inter in Latin in the number region the increase in size from top to bottom so you've got the lamina you got the pedicle again you have the spinous process or processes Sabinas in which you'll refer them you also have the superior articular process transfers process but this time it doesn't have any costal facets because no ribs attached here you have a superior superior inferior articular facet as well as a superiority confesses to which up and the vertebrae above and but below attach and you have a vertical frame and the frame in his important part because now small and triangular so the cervical one was large and triangular thoracic was swollen circular lumbar small and triangular again so now we have now let's take a look at the sacrum our favorite part which is most people leave this out but this is the you know the lumbar region sacrum is what holds the main way of the body and they hold a quiet large amount of weight of the body to keep him safe from his triangular shaped bone forms a posterior wall of the pelvis and it carries almost most amount of the way of the body and it's formed from five sacral vertebra fusing together.

Okay so there's a triangle shape and you've got a different lateral posterior and Furion see peer reviews and so there's five of them basically fuse together as one you know we're gonna go through the different parts so you have the ala which is this is where the psoas major muscles attach and the lumbar region you have the body of the sacrum you now have the lateral part which is important because this case groups for the sacral nerve as well as articulation joints with muscles and ligaments the base can sometimes be partially fused the sacrum you have thought to the surface to which the pelvis attaches to you also have a superior part to which the lumbar region attaches to the fifth lumbar vertebra touches.

Here you have a posterior sacral foramen you have a sacral canal through which the nerves and stable nerves run through no sacral hiatus was a bottom part now you have the different surfaces you have a dorsal surface which contains a median sacral crest as well as I mean medial sacral crest and the lateral okay so the key points is this attachment is sacrotuberous across ligaments so against do pause video and you know read or sunscreen because is way too and I've written all the information as much detail as I can and you can also read on the left where my mouse is pointing to as well so don't expect me to like speak across the whole thing really fast because the video is really fast and I've tried it put it and get it everything in with as much detail as possible so we have the final part final seconds of human form known as the colleagues and the only the first colleagues has a transfers process and none of them have lamina or a spine or pedicure or anything like that.

Okay so they're basically the tail bone and they're also you know a place so you've got a su eobseo vertebra one two three four and they're basically you know sites of attachments for like muscles like the anal Spinks the muscle the external saying explains the muscles as well as the gluteus maximus muscles you know those are the muscles that form the butt region of a human and yeah so once again I just like to apologize because I couldn't keep up with a video and I try to squeeze everything into under twenty minutes and please do pause a video and you know read the stuff on the screen and make sure you understand it for those of you didn't need those of you that need the latin version i've got it on the screen in brackets as well so did you read up on that make sure you go visit wo class college code at UK on our website and you'll find various different videos as well as sections where you can join up to so you go down to medicine you have all the different sections you have like the
cardiovascular or spydra so if you click into one of them you need to sign up and then you go the anatomy physiology biochemistry pathology.
