What are the two divisions of the Peripheral Nervous System?

• A. Sympathetic Nervous System and Parasympathetic Nervous System
• B. Somatic Nervous System and Autonomic Nervous System
• C. Central Nervous System and Peripheral Nervous System
• D. Motor Nervous System and Sensory Nervous System

Answer: (B)

The Peripheral Nervous System is organized into two broad divisions: the Somatic Nervous System and the Autonomic Nervous System. The somatic system handles voluntary movement and carries sensory information from the skin, muscles, and joints to the brain and spinal cord, then relays motor commands to skeletal muscles. The autonomic system regulates automatic functions like heart rate, digestion, and breathing, without conscious effort, and it splits into the sympathetic branch (prepares the body for action) and the parasympathetic branch (promotes rest and energy conservation).
