The peripheral nervous system (PNS) is one of the two main parts of the body’s nervous system. The central nervous system (CNS) is comprised of the brain and the spinal cord. The peripheral nervous system branches outside of the central nervous system and is comprised of nerves and neurons that transmit information to and from the brain.
The peripheral nervous system consists of 12 pairs of cranial nerves and 31 pairs of spinal nerves.
This allows the brain and spinal cord to both receive and send information to other areas of the body. In this way, it allows us to react to environmental stimuli. In the peripheral nervous system information is transmitted by bundles of nerve fibers or axons.This diagram with labels depicts and explains the details of Peripheral Nervous System Pictures.
