Nervous system Pocket Book


The nervous system is a complex network of nerves and cells that carry messages to and from the brain and spinal cord to various parts of the body. The nervous system includes both the central nervous system (CNS) and peripheral nervous system (PNS). The CNS is made up of the brain and spinal cord, and the PNS is made up nerves that connect the CNS to other parts of the body. The PNS is further subdivided into the somatic nervous system and the autonomic nervous system.
