In addition to supporting the head, the cervical spinal column also allows for the neck and head’s range of motion. Without it, the electrical impulses sent and received by spinal cord bleed off and nerves don’t get the messages, which can result in muscle spasms, twitching, numbness and more.

The spinal cord runs down the center of the protective spinal column extending from the neck to the lower back. This spinal canal is sandwiched between the intervertebral disk/body of the spine at the front and the “spinous process” at the back.The spinal cord itself has a protective myelin sheath that acts as insulation for individual nerves which increases nerve efficiency so signals from the brain can travel faster. Once they reach the spinal cord, they loop through and go straight back to the body part they came from. This bundle is called the cauda equina because it resembles a horse’s tail. Overgrowth of bone. Each nerve emerges in two short branches (roots): One at the front (motor or anterior root) of the spinal cord, One at the back (sensory or posterior root) of the spinal cord. The surrounding white matter contains columns of nerve fibers that carry sensory information to the brain from the rest of the body (ascending tracts) and columns that carry motor impulses from the brain to the muscles (descending tracts). The main areas of the brain include the: cerebrum (also called the Forebrain) cerebellum (also called the Hindbrain) brainstem; The cerebrum. Like the brain, the spinal cord is covered by three layers of tissue (meninges).
