Peripheral Nervous System (PNS): Divisions and Roles
The Peripheral Nervous System (PNS) connects the central nervous system to the rest of the body. It consists of the somatic and autonomic nervous systems, regulating voluntary and involuntary functions.

Peripheral Nervous System (PNS): Divisions and Roles
The human nervous system is an intricate network responsible for regulating body functions, processing sensory input, and enabling responses to environmental stimuli. The Peripheral Nervous System (PNS) is one of its essential components.
What is the Peripheral Nervous System?
The PNS comprises all nerves outside the brain and spinal cord. It connects the Central Nervous System (CNS) to limbs and organs, facilitating communication between the body and brain.
Divisions of the PNS
- Somatic Nervous System (SNS): Controls voluntary movements of skeletal muscles and relays sensory information.
- Autonomic Nervous System (ANS): Regulates involuntary functions, such as heartbeat, digestion, and respiration.
Roles of the PNS
The PNS plays a crucial role in sensory perception, motor function, and autonomic responses. It ensures seamless interaction between internal and external environments.
