Central Nervous System
The central nervous system (CNS) is made up of the brain, the spinal cord, and the optic nerves. The central nervous system controls thought processes, guides movement, and registers sensations throughout the body.
- The spinal cord serves as a conduit for signals between the brain and the rest of the body. It also controls simple musculoskeletal reflexes without input from the brain.
- The brain is responsible for integrating most sensory information and coordinating body function, both consciously and unconsciously.
