Accepted Answer

The two principal divisions of the nervous system are the peripheral nervous system (PNS) and the central nervous system (CNS). The PNS consists of all the nerves and ganglia outside the brain and spinal cord, while the CNS is made up of the brain and spinal cord. The sympathetic and parasympathetic divisions are subdivisions of the autonomic nervous system, which is part of the PNS.
