The central nervous system is one of the two principal divisions of the body's nervous system. The nervous system is the body's communication network and control center. The central nervous system (CNS), consisting of the brain and the spinal cord, is the control center for the entire nervous system. All the sensations of the body are relayed to the central nervous system. All nerve impulses that cause muscles to contract and glands to secrete come from the central nervous system. As a medical specialist, it is of vital importance for you to understand the complex functions of the central nervous system.

Occasional references to military terminology or combat situations do not detract from the lesson's relevance for civilian medicine and health care.
