One of the major eleven organ systems of the human body is the nervous system. This system is responsible for controlling and maintaining the coordination among all other organ systems. The organs making up the nervous system are the brain and the spinal cord. The nerves are also a part of the nervous system which connects the organs of this system to all other body parts. The specialized cells which make up the nervous system are the neurons and the glial cell. These neurons have special ability to generate electrical signals through action potential which are then transmitted to the other body parts by the neurotransmitters. The glial cells are responsible for the formation of myelin sheath around the axon of the nucleus which acts as an insulator and increases the rate of transmission of the nervous signals.
