to be able to move your head up and down
Body of the vertebra. It is fused with the Axis vertebra. Axis being the second vertebra.
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.
Since the dens is part of the Axis vertebra (and project up in the first vertebra, the Atlas vertebra that supports the skull) it is called the Dens Axis
2nd cervical vertebra (axis) has dens (also called odontoid process).
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.
The name of the second vertebrae is called the axis.

Vertebra 2
Actually, the first cervical vertebra is called the atlas, not the axis. The axis is the second cervical vertebra that forms a pivot joint with the atlas, allowing for rotation of the head from side to side.
Since the dens is part of the Axis vertebra (and project up in the first vertebra, the Atlas vertebra that supports the skull) it is called the Dens Axis
axis the second cervical vertebra.
The name of the second vertebrae is called the axis.
2nd cervical vertebra (axis) has dens (also called odontoid process).
The axis has a dens, which provides a pivot for the atlas.
The Axis is the second vertebra in your spinal column right at the top.
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."
