Cervical Vertebrae

VideoRotating Model
Read this description and then try to find the structures. Note, you can enlarge at any time by hitting the enlarge button (4 arrows), but you lose this text. The blue plus mark will give you a labeled picture from a lateral view. I don't suggest hitting in the enlarged view on the labed picture. It goes past the screen, at least on my computer.

Hit stop on the auto rotation. Grab the picture by clicking the mouse and rotate in so the spinous process , which as the number 2 on it, is pointing to your right. Then rotate it right, by dragging your mouse left, just a little more unit you see start to see the 11 on the transverse process.

In this view, you are looking at 2 cervical vertebrae with an interverteberal disc between them. The spinous process which is on your right is posterior and the body, which is on your left, is anterior. The transverse process is facing you. You should be able to see the transverse foramen of the lower vertebra from this view as well. Try to find the facets on the top and bottom of the transverse process. These are the superior and inferior articulating facets. You can click on the blue plus to cheat if you don't see them. Pay attention to how the inferior articulating facet of the top vertebra fits nicely on the superior articulating facet of the bottom vertebra.

Rotate the picture back and forth until you can see the foramen between the 2 vertebrae. If you hit the plus button, you are can see moew clearly This foramen is called the intervertebral foramen and this is where spinal nerves exit. If the intervertebral disc slips, this foramen becomes smaller and it could pinch a nerve. This typically happens in the lumbar region.

Keep rotating the picture to the right and try to find the landmarks on the other side. Keep going until you are looking at the posterior view. You will notice that the spinous process is short and bifidal which means there are 2 points with a cleft between them.
