Detailed explanation-1: -The nervous system uses tiny cells called neurons (NEW-ronz) to send messages back and forth from the brain, through the spinal cord, to the nerves throughout the body. Billions of neurons work together to create a communication network. Different neurons have different jobs.

Detailed explanation-2: -Nerves are like cables that carry electrical impulses between your brain and the rest of your body. These impulses help you feel sensations and move your muscles. They also maintain certain autonomic functions like breathing, sweating or digesting food. Nerve cells are also called neurons.

Detailed explanation-3: -The main part of the cell, the part that carries on the general functions, is the cell body. Dendrites are extensions, or processes, of the cytoplasm that carry impulses to the cell body. An extension or process called an axon carries impulses away from the cell body.

Detailed explanation-4: -The nervous system transmits signals between the brain and the rest of the body, including internal organs.

Detailed explanation-5: -Messages, in the form of electrical impulses, constantly travel back and forth between the brain and other parts of the body. A special cell called a neuron is responsible for carrying these messages.
