ANATOMY

Detailed explanation-1: -The first cervical vertebra is a bony ring with a thin anterior arch and posterior laminae, which are joined by lateral masses having articular facets that articulate with the occipital condyles superiorly and the lateral masses of C2 inferiorly.

Detailed explanation-2: -Your first vertebra (C1), also called the atlas, is a ring-shaped bone that begins at the base of your skull. It’s named after Atlas, of Greek mythology, who held the world on his shoulders. The atlas holds your head upright.

Detailed explanation-3: -Introduction. The Atlas (the first cervical vertebra-C1) differs from the other cervical vertebrae in that it has no body or spinous process. It is comprised of two bony arches with two bony masses laterally. It articulates with the Occiput above and C2 (the Axis) below.

Detailed explanation-4: -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. That is true of the C1 atlas as well.

Detailed explanation-5: -The atlas bone is the first of seven cervical vertebrae (vertebra cervicalis I or C1). It supports the weight of the skull. The name for the bone was derived from a deity of Greek mythology called Atlas, who supported the heavens. On the superior surface of the atlas bone are a pair of concave facets.
