Cervical spine

The cervical spine is the uppermost section of your spine, made up of seven vertebrae that run through your neck and support the weight of your head while allowing a wide range of movement.

What your cervical spine does — from C1 to C7 — and why it's vulnerable

Your cervical spine starts at the base of your skull and extends down to where your neck meets your upper back. Those seven vertebrae — labeled C1 through C7 — carry the weight of your head, which averages around 10 to 12 pounds, and they do it while allowing you to turn, tilt, and nod in nearly every direction. That combination of load and mobility makes the cervical spine one of the most mechanically demanding regions of the body.

The spinal cord passes through a channel in these vertebrae, and nerves branch out from between each level to supply sensation and muscle control to your shoulders, arms, and hands. When something compresses or irritates those structures — whether from disc changes, joint wear, or muscle tension — you can feel it far from your neck.

What goes wrong in the cervical spine and why

Degenerative changes in the cervical spine are common with age, but they don't always cause symptoms. Disc herniation, bone spur formation, and joint stiffness can all develop gradually, often from years of posture patterns, repeated strain, or injury. Whiplash from a sudden impact is another common source of cervical spine injury. Stiffness, headaches at the base of the skull, and pain or tingling that radiates into the shoulder or down the arm are among the most frequent signs that the cervical spine is involved.

Why cervical spine pain is frequently attributed to the wrong cause

Headaches originating from the cervical spine are often mistaken for tension or migraine headaches, and arm symptoms are sometimes blamed on the shoulder or elbow before anyone looks at the neck. A careful assessment that traces the symptom pattern back to its source changes what's treated — and what actually gets better.
