What You Should Know About the Peripheral Nervous System
What exactly is the peripheral nervous system and what role does it play in the body? First, it is important to realize that the nervous system is divided into two parts: the central nervous system and the peripheral nervous system. The central nervous system includes the brain and spinal cord, while the peripheral nervous system includes all of the nerves that branch out from the brain and spinal cord and extend to other parts of the body including muscles and organs. Each part of the system plays a vital role in how information is communicated throughout the body.
