The central nervous system (CNS) is made up of the brain and the
spinal cord. The central nervous system controls thought processes, guides
movement, and registers sensations throughout the body.
The spinal cord is a single continuous structure that goes from the
brain through the base of the skull and down the spinal column. Individual
paired spinal nerves continue down to the tailbone.
Injuries or diseases that affect the central nervous system can
sometimes cause permanent loss of function and disability.
