The nervous system is made up of millions of neurons and interconnected nerves that are comparable to a wiring system. The nervous system is composed of the central nervous system (CNS) and the peripheral nervous system (PNS). The nervous system functions like a corporate giant. The CEO is the leader in the CNS and the officers and delegates are the PNS. The CNS gives the commands and the PNS follows the commands. The Central Nervous System The central nervous system (CNS) is

the control of the body and communication among its parts. The brain and spinal cord form the control center known as the central nervous system (CNS)‚ where information is evaluated and decisions made. The sensory nerves and sense organs of the peripheral nervous system (PNS) monitor conditions inside and outside of the body and send this information to the CNS. Efferent nerves in the PNS carry signals from the control center to the muscles‚ glands‚ and organs to regulate their functions. Functions
