The Nervous System
Our body movement and co-ordination is controlled by our nervous system. Our nervous system communicates with our body by nerves and neurons which transmit signals through out our whole body. We have two nervous systems which enable us to function properly. The central nervous system is made up of the brain, spinal cord and retina. The peripheral nervous system consists of sensory neurons and nerves which connect with each other and the central nervous system. Check out below for a further look into our body' s main control system.
