Peripheral nervous system (PNS)
The nerves, which make up the central nervous system, are colored green. The cranial nerves are not visible in this diagram
Peripheral Nervous system (PNS)
Peripheral nerves are cord-like structures that look pale, white and shiny and are found in every part of the body besides the CNS.
The PNS plays the role of linking parts of the body to the CNS.
The PNS consists of 12 pairs of cranial nerves that arise from the brain and 31 pairs of spinal nerves that emerge from the spinal cord. These spinal nerves branch out at junctions on the spinal cord known as nerve roots. These two types of nerves carry nerve impulses into and out of the CNS.
