What is the role of the peripheral nervous system (PNS)?

The peripheral nervous system (PNS) plays a crucial role in bridging the central nervous system (CNS) and the rest of the body by conveying motor commands from the brain and spinal cord to the muscles, enabling movement. Additionally, it carries sensory information back to the CNS from sensory receptors located throughout the body. This dual function ensures that the body can respond to external stimuli and execute voluntary and involuntary movements.

In essence, the PNS is essential for facilitating communication within the body, allowing for both sensory perception and motor function. Other options, such as regulating hormonal functions, controlling immune responses, or processing visual and auditory information, do not accurately encapsulate the primary responsibilities of the PNS, as these functions are primarily associated with other systems or specific brain areas.
