Detailed explanation-1: -The cervical spine, comprised of seven cervical vertebrae referred to as C1 to C7, is divided into two major segments: the craniocervical junction (CCJ) and the subaxial spine. The CCJ includes the occiput and the two most cephalad cervical vertebrae, known as the atlas (C1) and the axis (C2).

Detailed explanation-2: -The first two cervical vertebrae are named the atlas (C1) and the axis (C2). Unlike all other vertebrae, the atlas and axis of most mammals are not separated by an intervertebral disk but rather by a synovial joint, similar to the skull-atlas joint (Fig.

Detailed explanation-3: -Overview. The cervical spine is made up of 7 vertebrae. The first 2, C1 and C2, are highly specialized and are given unique names: atlas and axis, respectively. C3-C7 are more classic vertebrae, having a body, pedicles, laminae, spinous processes, and facet joints.

Detailed explanation-4: -The atlas and axis vertebrae are the two most superior bones in the vertebral column, and they are part of the seven cervical vertebrae. The atlas is the top-most bone, sitting just below the skull; it is followed by the axis. Together, they support the skull, facilitate neck movement, and protect the spinal cord.

Detailed explanation-5: -The most common explanation why the first cervical vertebra is called atlas is that the vertebra holds up the globe of the cranium the way Atlas holds up the globe of the heavens. However, an important part of the myth of Atlas is that the Titan was being punished.
