#Cervical spine anatomy series

The vertebra and discs form the spinal column from the head to the pelvis, giving. It is made up of bony segments called vertebrae with fibrous tissue called intervertebral discs between them. The first cervical vertebra is unique, as it is a ring, called the atlas, that rotates around part of the second vertebrae, the axis. The spine, also called the back bone, plays a vital role in stability, smooth movement and protection of the delicate spinal cord. In general, the younger the child, the more likely an upper cervical spine injury will occur.

transverse foramina protecting the vertebral arteries and veinsĪ more detailed description can be found in the article on typical cervical vertebrae. The cervical spine, or neck, begins at the base of the skull and through a series of seven vertebral segments connects to the thoracic, or chest, region of the spine. The anatomy of the developing cervical spine predisposes children to injury of the upper cervical spine.

relatively long, bifid (except for C7) inferiorly pointing spinous processes.

relatively wide vertebral arch with large vertebral foramen.

Gross anatomyĪlthough C1 (atlas) and C2 (axis) have unique characteristics and C7 (also termed vertebra prominens) deviates from the overall pattern, general characteristics of the cervical vertebrae include: These three parts consist of 24 vertebrae and form the S.

It also provides a pathway for the vertebral arteries and veins to carry blood to and from the brain via the transverse foramina.įor a basic description of the anatomy of a generic vertebra, see vertebrae. The cervical spine, the thoracic spine and the lumbar spine are known together as the spinal curve. Its main function is to support the skull and maintain the relative positions of the brain and spinal cord. The anterior cervical area is covered with muscles that run from the rib cage and collar bone to the cervical vertebrae, jaw, and skull. The cervical spine (often shortened to C-spine) is the upper part of the spine extending from the skull base to the thorax at the level of the first vertebra with a rib attached to it. The cervical spine is the upper portion that includes the neck a cervical curvature refers to an atypical curve located along the cervical portion of the spine. The spine, also called the backbone, plays a vital role in stability, smooth movement and protection of the delicate spinal cord.
