Which nervous system division is responsible for conscious actions?

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

Answer: (B)

Conscious actions come from voluntary control of skeletal muscles, which is the job of the somatic nervous system. It sends motor commands from the brain and spinal cord to skeletal muscles and handles the sensory signals we can consciously notice, enabling deliberate movements. The autonomic nervous system governs involuntary functions like heart rate and digestion, usually outside conscious control. The central nervous system (brain and spinal cord) processes and integrates information, but the execution of voluntary actions is carried out by the somatic division of the peripheral nervous system.
