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 consists of nerves and ganglia that transmit signals between the central nervous system and limbs, organs, and skin. The PNS is divided into two main parts: the somatic nervous system, which controls voluntary movements, and the autonomic nervous system, which regulates involuntary functions like heart rate and digestion. The PNS plays a crucial role in sensory perception and motor control. It allows the body to respond to external stimuli, such as touch and temperature, and helps maintain homeostasis by managing internal processes. Overall, the PNS is essential for communication between the brain and the body, ensuring proper functioning and coordination.
