Cervical

The upper spine (neck) area of the vertebral column. This section consists of seven vertebra or bones, and are referred to as C1-C7. These vertebrae are smaller in size when compared to other spinal vertebrae. The purpose of the cervical spine is to contain and protect the spinal cord, support the skull, and enable diverse head movement ( rotate side to side, bend forward and backward).

Spinal Cord and Cervical Nerve Roots

Nerve impulses travel to and from the brain through the spinal cord to a specific location by way of the peripheral nervous system (PNS). The PNS is the complex system of nerves that branch off from the spinal nerve roots. These nerves travel outside of the spinal canal or spinal cord into the organs, arms, legs, fingers – throughout the entire body.

The cervical nerves control many bodily functions and sensory activities.
