Peripheral Nervous System


The peripheral nervous system is all of the nervous system that is not the central nervous system (brain and spinal chord). Anatomically, this includes cranial and spinal nerves projecting to and from the central nervous system, as well as ganglia (collections of cell-bodies) and sensory receptors. In terms of general function, the peripheral nervous system is commonly divided into the somatic, autonomic and enteric nervous systems. The enteric nervous system controls gastrointestinal function.
