Peripheral Nervous System – FAQ

What is the Peripheral Nervous System (PNS)?

The Peripheral Nervous System (PNS) consists of all the nerves outside the brain and spinal cord. It connects the central nervous system (CNS) to limbs and organs, facilitating communication throughout the body. Essentially, it acts as a relay between the brain and spinal cord and the rest of the body.
