The nervous system is divided into two parts:Central and Peripheral.The Central consist of two body parts;Brain and Spinal Cord.The Peripheral only consist of the sensory neurons and motor neurons.The Brain is the center of the nervous system .It is located in the head.It send messages to the body when to listen,see,balance,taste,touch,and smell.The Peripheral Nerves connects the central nervous system to the limbs and organs.Sensory neurons that transmit information to the central nervous system from the five senses.Inter neurons relay signals between neurons or groups of neurons, are responsible for the processing of information by the brain.Motor neurons relay signals from the central nervous system to the other parts of the body. Signal transmission-Neurons are cells specialized for communication.
