What is "peripheral nervous system"?

The peripheral nervous system is a network of nerves and ganglia that extends from the central nervous system to the rest of the body. It includes all the nerves outside of the brain and spinal cord. The peripheral nervous system serves as a communication system, transmitting signals between the central nervous system and the various organs, muscles, and tissues throughout the body. It is responsible for sensory input, motor control, and the regulation of bodily functions. The peripheral nervous system plays a vital role in allowing us to perceive and interact with our environment, coordinate voluntary movements, and maintain homeostasis.
