Which component is responsible for all voluntary body action?

• A. Peripheral nervous system
• B. Autonomic nervous system
• C. Enteric nervous system
• D. Central nervous system

Answer: (D)

All voluntary movements are planned and initiated by the brain and spinal cord, which make up the central nervous system. The CNS decides what action to take and sends motor commands through peripheral nerves to the skeletal muscles to carry out the movement. The autonomic and enteric nervous systems handle involuntary processes like heart rate and digestion, not voluntary actions. So the central nervous system is the control center responsible for initiating and coordinating voluntary body action.
