Peripheral Nervous System

The peripheral nervous system (PNS) is a part of the nervous system that connects the brain and spinal cord to the rest of the body. It includes all the nerves outside the central nervous system (CNS) and is responsible for transmitting signals between the CNS and limbs, organs, and skin. The PNS has two main divisions: the somatic nervous system, which controls voluntary movements and sensations, and the autonomic nervous system, which regulates involuntary functions like heart rate and digestion. Together, these systems help the body respond to stimuli and maintain homeostasis.
