Nervous System

The Nervous System is the body's electrical wiring. It consists of the brain, spinal cord, and retina. It causes you to feel pain, and emotions. It's basically in charge of how the muscles move, how you feel emotions, and much more in the body. Head injuries can cause major problems in the nervous system, and the brain in general. Motor Neurone Disease causes your muscles to weaken, and is effective in the spinal cord.
