There are three categories of nervous systems. The central nervous system includes the brain and spinal cord. Its function is to receive sensory information and transmit motor skills. The peripheral nervous system contains 31 pairs of spinal nerves and 12 pairs of cranial nerves that transmit sensory and motor nerves to and from the CNS. The autonomic nervous system controls, regulates, and coordinates visceral activities on an unconscious level.
