Understanding The Anatomy of Your Back & Neck
Technically your neck is called the cervical spine, which begins at the base of the skull. It contains 7 small vertebrae (bones), which doctors label C1 to C7 (the ‘C’ means cervical). The numbers 1 to 7 indicate the level of the vertebrae. C1 is closest to the skull, while C7 is closest to the chest. In between each vertebra are tough fibrous shock-absorbing pads called the intervertebral discs. Each disc is made up of a tire-like outer band and a gel-like inner substance.
The parts of the cervical spine are quite complex. In addition to bones and discs, it includes the upper region of the spinal cord, 8 nerve roots, an elaborate system of arteries and veins, 32 muscles for strength, and numerous ligaments. The joints, muscles, and ligaments assist with movement and stabilize the neck. |
