The nervous system is the main control center for the entire body. It sends and receives messages using electrical* impulses that are passed between nerve cells called neurons.
The nervous system is made up of two parts:
- The central nervous system includes the brain and spinal cord.
- The peripheral nervous system includes a large group of nerves throughout the body.
- Orders are sent from the brain to body organs and tissues along motor neurons*.
- Information about the condition of the body or the environment is sent to the brain along sensory neurons*. This information is obtained using the 5 senses.
