37) Intervertebral discs are composed of an inner semifluid nucleus pulposus, which gives the discs elasticity and
compressibility, and a covering of fibrocartilage, the annulus fibrosus, which limits expansion and holds successive
vertebrae together.
38) The atlas or C1 vertebra has no body. It articulates with the skull with large curved articular surfaces to allow the
skull to rock in a "yes" motion. The axis or C2 vertebra has a dens that allows the axis to pivot, giving the head the
"no" motion. The vertebral foramen of the atlas is enlarged so that when the head is pivoted in the "no" motion, the
spinal cord can move.

41) The hyoid acts as an attachment point for muscles in the throat region to connect the muscles in the lower jaw
region. It allows for the muscles to make a right angle at the junction of the lower jaw and throat. The hyoid serves
as a movable base for the tongue and its horns are attachment points for neck muscles that raise and lower the
larynx during speech and swallowing.
42) These processes (superior and inferior) allow the vertebral column to flex forward some, but lock the vertebrae if
the column is flexed back. In a four-legged animal, such as a horse, these processes allow the back to remain in
place while you ride it.
