What is Neck Anatomy?
The anatomy of the neck, or cervical spine, includes the spinal structure from C1 to C7. The cervical spine supports the skull and acts as the conduit for the spinal cord. The C1 vertebrae, known as the atlas bone, begins at the base of the skull. Together, C1 and C2 facilitate 50% of motion for the head. C7 is the last vertebrae in the neck and it connects to T1, which is the first vertebrae in the thoracic spine.
