The Peripheral Nervous System (PNS) is a network of nerves extending from the brain and spinal cord to the rest of the body. It serves as a communication relay between the brain and spinal cord (the central nervous system) and the limbs and organs. The PNS is crucial for motor functions (controlling muscle movements) and sensory functions (transmitting sensory information like touch, pain, and temperature to the brain). It enables our interactions with the external environment and plays a vital role in bodily functions and reactions.
