APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -The atlas (plural: atlases) is the first cervical vertebra, commonly called C1 . It is an atypical cervical vertebra with unique features. It articulates with the dens of the axis and the occiput, respectively allowing rotation of the head, and flexion, extension and lateral flexion of the head.

Detailed explanation-2: -The C1 atlas is the uppermost cervical vertebra of the spine. It supports the head and-along with the C2 axis, the cervical vertebra just below it-allows the head to nod and rotate from side to side. At birth, children have softer bones.

Detailed explanation-3: -The atlas is the first vertebra of the vertebral column, located in the most superior portion of the cervical region of the vertebral column. The atlas articulates superiorly with the occipital condyles found on each side of the foramen magnum of the skull.

Detailed explanation-4: -The first cervical vertebra, atlas, is unique in the sense that it possesses neither a body nor spinous process. It consists of an anterior and posterior arch extending between two lateral masses, forming a closed triangular ‘ring’ that accommodates the brainstem.
