The Nervous System

A human has a nervous system with about 60,000,000,000 nerve cells. The nervous system controls your body's communication system. A nerve is a fibre or a bundle of fibres through which impulses especially of sensation and motion pass between the brain ot spinal cord, and the eyes, ears, muscles, glands, etc. Millions of nerves signal to enter your brain every single second. In many places, sensory nerves ( which carry sense signals from the body to the brain) run alongside the moter nerves ( which carry the brains commands telling the muscles to move). The nervous system has 3 main parts, the central nervous system, the peripheral nervous system , and the autonomic nervous system. Each one of these parts has a special function. The central nervous system is the brain or spinal cord, it is made up of the nerves that branch out to the central nervous system. c.n.s is the abreviation for the central nervous system. The nervous system is a very important system within a system in our body. Without it we would not be able to move, think, or feel.
