PNS stands for

PNS stands for

• A. Peripheral Nervous System
• B. Central Nervous System
• C. Parasympathetic Nervous System
• D. Primary Nervous System

Answer: (A)

Identifying what PNS stands for is the main idea here. The Peripheral Nervous System includes all nerves and ganglia outside the brain and spinal cord. It serves as the communication link between the CNS and the rest of the body, carrying sensory information from the body to the brain and conveying motor commands from the brain to muscles. It contains the somatic nervous system, which controls voluntary movements, and the autonomic nervous system, which regulates involuntary functions like heart rate and digestion. The Central Nervous System, in contrast, is the brain and spinal cord themselves. The Parasympathetic Nervous System is a division within the autonomic branch of the PNS, not the entire system. A term like Primary Nervous System isn’t standard.
