The nervous system is made up of nerve cells or neurons that are "wired" together throughout the body, somewhat like communication system. Neurons carry messages in the form of an electrical impulses. The messages move from one neuron to another to keep the body functioning. Neurons have a limited ability to repair themselves. Unlike other body tissues, nerve cells cannot also be repaired if damaged due to injury or disease. |
