The nervous system controls our bodies like we control a bike. It controls our tasting, smelling, seeing, hearing, thinking, dreaming, breathing, heart beating, moving, running, sleeping, laughing, singing, remembering, feeling pain or pleasure, painting, writing much more.The nervous system also controls our senses. Without the nervous system we could not live. Nerves are in every part of the body. The nervous system is very similar to the endocrine system.

The spinal cord is part of the nervous system. Without the spinal cord we could not live because we wouldn't be able to breathe. If the spinal cord is damaged our nerves wouldn't work.

The nerves send messages throughout our bodies. For example, if we hurt ourselves the nerves send a message to the brain so we can feel pain. Nerves are like narrow threads or flexible cables. There are billions of nerves in our bodies. If one persons nerves were lined up the line would be as long as 600 miles.

Without your brain you could not live. Brain surgeons say that the brain is similar to the white of a boiled egg. The cerebrum is the biggest part of the brain.
