What is the function of the cervical spine in the neck?

The cervical spine, which consists of seven vertebrae located in the neck, plays a crucial role in supporting the head while concurrently protecting the spinal cord. This region of the spine is structured to provide both stability and a range of motion, allowing for the flexibility needed for head movements such as nodding and turning. By enveloping and safeguarding the spinal cord running through it, the cervical spine helps prevent potential injuries from impacts or trauma, which could otherwise compromise neural function. The design of the cervical spine is integral to maintaining the balance between mobility and protection, making it essential for overall physical function and health in the upper body.
