Answer
The dens allows the head to pivot left and right.
Solution
1. The head pivots on the axis (the second cervical vertebra) around a structure called the odontoid process or dens.
2. The dens projects upward from the body of \(C2\) and acts as a pivot for the atlas (the first cervical vertebra), allowing the head to rotate left and right.
3. Thus, the structure that allows this movement is the dens.
Answer: C) Dens

The part of the axis that allows you to pivot your head left and right, as if to say "no", is the Dens. This unique bony structure acts as a pivot point for the first cervical vertebra (the atlas), enabling that distinctive rotational motion of the head. Fun fact: The axis and the atlas are like the dynamic duo of your spine, designed for both stability and mobility. They work together to support your head's movement in various directions, helping you see everything's a “yes” or a “no” in your world!
