The main functions of the cervical spine are to support the skull, provide mobility for the spine and protect the spinal cord, according to Healthline. The cervical spine is located at the upper portion of the spinal column.
The cervical spine comprises seven cervical vertebrae, states Healthline. These vertebrae are located in the neck and are numbered C1 through C7. These vertebrae help the neck move properly and connect to the skull in order to provide support and mobility to the head. There are also many ligaments and tissues around the cervical spine in order to help it with its functions.
