| an exceptionally well-organized system that is responsible for coordinating all the many activities that are preformed by the body. | nervous system |
| Scientific study of the structure, function and pathology of the nervous system | Neurology |
| This consists of the brain, spinal cord , spinal nerves and cranial nerves | Central Nervous System (CNS) |
| Controls consciousness and mental activities involuntary functions of the 5 senses (seeing, hearing, feeling, smelling and tasting) as well as voluntary muscle actions including all body movements and facial expressions. | Central Nervous System (CNS) |
| A system of nerves that connects the peripheral (outer) parts of the body to the CNS, it has both sensory and motor nerves | Peripheral Nervous System (PNS) |
| This functions to carry impulses or messages to and from the central nervous system | Peripheral Nervous System (PNS) |
