The toothlike process on the upper surface of the axis, which articulates with the CERVICAL ATLAS above.

The first cervical vertebra.

The joint involving the CERVICAL ATLAS and axis bones.

In anatomy, 'axis' is a term used to describe a real or imaginary line around which something rotates or along which it aligns, such as the second cervical vertebra, also known as the axis bone, which provides the pivot point for the rotation of the head.

Acute and chronic conditions characterized by external mechanical compression of the SPINAL CORD due to extramedullary neoplasm; EPIDURAL ABSCESS; SPINAL FRACTURES; bony deformities of the vertebral bodies; and other conditions.
