 Okay, so let's look at the vertebrae themselves. Okay, so our cervical vertebrae. We have seven of these We have 12 thoracic vertebrae and five lumbar vertebrae So the common phrase for this is breakfast at seven lunch at 12 dinner at five Okay, so remember 7 12 and 5 Now the cervical vertebrae The first two cervical vertebrae are kind of special You have the Atlas which is C1 and the axis So our atlas looks like this. So it's very flattened. It's actually what articulates with the skull itself Okay, so it has some of the main characteristics that we see on all the other vertebrae So you can see the large hole here. So this is our vertebral foramen It's also got the characteristics that we find with cervical vertebrae. Do you see these transverse foramen off to the sides? Okay, so that's our flat Atlas our axis on the other hand Not so flat. We can see it actually has this large Protruberance coming off the top there called the dins So this dins articulates something like that Okay We can see it still has The vertebral foramen the transverse foramen so we know it's cervical And now we're actually starting to see this other form the spinous process Sticks off the front there. So all our other cervical vertebrae Look something like this So you have the body Ritibal foramen transverse foramen You can see the spinous process the cervical vertebrae also have a biphyde process So it's kind of split into there Okay, we can now look at the Thoracic vertebrae so again, we have a body it's a larger of course than our cervical You've got this very downward protruding Spinous process you can see it's no longer biphyde. It's just singular there And then compare that to our large lumbar vertebrae here. So let's look and kind of compare You can see the body there is exponentially larger in our lumbar. It's huge comparatively speaking You've got a large Spinous process. It's not nearly as downward protruding as an orthoracic vertebrae
