What cervical vertebra has a tooth-like projection on its superior surface?
The second cervical vertebra (C2), also called the axis, has a projection on it's superior surface called a dens that creates a pivot joint with the vertebra above it (C1), also known as the atlas. The pivot joint between these two vertebra allows 45 degrees of rotation in each direction, which is half the possible rotation of the head.
Dens here provides a pivot for rotation of the first cervical vertebra?
Atlaswrong . the correct answer is axis (http://en.wikipedia.org/wiki/Axis_(anatomy)) "It forms the pivot upon which the first cervical vertebra (the atlas), which carries the head, rotates."
What is another name for the second cervical vertebra?

When the head is moved from side to side the first vertebra pivots around the?
When the head is moved from side to side, the first vertebra pivots around the second vertebra called the axis. This movement allows for rotation and flexibility of the neck.
What does the first vertebra pivot around when head moves side to side?
The first cervical vertebra, called the atlas, pivots around the second cervical vertebra, known as the axis, when the head moves from side to side. This unique joint allows for the head's rotational movements.

What part of the vertabrea controls head movement?
The atlas vertebra (C1) controls the rotation of the head from left to right, while the axis vertebra (C2) allows for nodding or shaking of the head up and down. Together, these vertebrae form the upper cervical spine, which is responsible for a significant portion of head movement.

Where is the axis located in your body it sits on a bone?
The axis is the second cervical vertebra in the spine, located just below the atlas (the first cervical vertebra). It is named after its function as it allows the head to rotate on top of the spine.
When the head is moved from side to side the first vertebrae pivots around the what of the second vertebrae?
When the head is moved from side to side, the first vertebra (atlas) pivots around the dens (odontoid process) of the second vertebra (axis). This motion allows for the rotation and flexibility of the neck.
