Nervous System

Nervous system is the system that controls all others systems of the body.

The nerves carry the messages from all parts of the body to the brain through the spinal cord. The eyes, nose, ears and the mouth need the help of the nervous system to work. 

Your brain is the most remarkable organ in your body. It is protected by the skull. It looks like walnut and is the control center of the whole body. It stores a lot of information and can recall it when needed. This is called memory.

Your brain has three main regions; the cerebrum, the cerebellum, and the brain stem.
