The second cervical vertebra, also known as the axis, has a tooth-like projection called the odontoid process (dens) on its superior surface. This structure allows for rotation of the head in conjunction with the atlas vertebra.
Yes, the dens is a bony projection on the axis (C2 vertebra) that acts as a pivot point for the rotation of the first cervical vertebra (atlas) in the neck. This specialized structure allows for the nodding motion of the head.
The second cervical vertebra is also known as the axis vertebra. It is a unique vertebra as it allows for rotation of the head.
No, the atlas bone does not have a spinous process. It is the first cervical vertebra that supports the skull and allows for nodding movements of the head.
The first cervical vertebra is called the atlas, after the Greek mythological figure who held up the heavens. The second cervical vertebra is called the axis, as it allows the head to rotate from side to side.
The axis is the second cervical vertebra of the spine located in the neck. Its most distinctive feature is the dens (odontoid process), which serves as a pivot for rotation of the first cervical vertebra (atlas). This allows the head to turn from side to side.
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 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.

The second cervical vertebra, also known as the axis, has a tooth-like projection called the odontoid process (dens) on its superior surface. This structure allows for rotation of the head in conjunction with the atlas vertebra.
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.
Yes, the dens is a bony projection on the axis (C2 vertebra) that acts as a pivot point for the rotation of the first cervical vertebra (atlas) in the neck. This specialized structure allows for the nodding motion of the head.
The second cervical vertebra is also known as the axis vertebra. It is a unique vertebra as it allows for rotation of the head.
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.
No, the atlas bone does not have a spinous process. It is the first cervical vertebra that supports the skull and allows for nodding movements of the head.
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.
