APPLIED RADIOLOGICAL ANATOMY

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.

Detailed explanation-2: -The C7 is usually identified by a long, club-shaped and unbranched SP (1–3), referred to as vertebra prominens (4). The C7 represents the bottom of the cervical spine and connects with the top of the thoracic spine, T1, to form the cervicothoracic junction, also referred to as C7-T1.

Detailed explanation-3: -In the cervical segments, there are 7 cervical vertebrae and 8 cervical nerves (Figure 3.2). C1-C7 nerves exit above their vertebrae whereas the C8 nerve exits below the C7 vertebra. It leaves between the C7 vertebra and the first thoracic vertebra.

Detailed explanation-4: -Seven cervical vertebrae, labeled C1 to C7, form the cervical spine from the base of the skull down to the top of the shoulders.

Detailed explanation-5: -The main function of the cervical vertebrae is to protect your spinal cord. The seven bones stacked upon one another form a bony tunnel for your spinal cord to travel through. The articulation of two bones creates a small hole, called a foramen, through which your peripheral spinal nerves travel.
