What is the nervous system?


 

The nervous system is made up of billions of tiny nerve cells that carry electrical signals throughout the body.



It consists of two parts: the central nervous system and the peripheral nervous system. The central nervous system is the brain and the spinal cord, which extends from the base of the brain all the way down your back. It is protected by rings of bone in your spine, called vertebrae. The peripheral nervous system is the network of small nerves that extends to all parts of the body. The nervous system is the body’s main communication network, helping the whole system to work properly.
