The cervical region refers to the part of the spine located in the neck, consisting of seven vertebrae labeled C1 to C7. This area supports the head, allows for a wide range of motion, and protects the spinal cord, which runs through the vertebral column. The cervical vertebrae are smaller and more flexible than those in other regions of the spine, enabling movements like nodding and rotation. In addition to the vertebrae, the cervical region contains important structures such as nerves, muscles, and blood vessels. The cervical plexus is a network of nerves that supplies sensation and motor function to the neck and parts of the upper body. Proper function of the cervical region is essential for overall mobility and health.
