Which nervous system division is considered voluntary control?

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

Answer: (A)

Voluntary control refers to consciously directing skeletal muscles. The somatic nervous system handles this by sending motor commands from the brain to skeletal muscles and by relaying sensory information back to the brain, enabling deliberate actions like reaching, walking, or speaking. In contrast, the autonomic nervous system governs involuntary processes such as heart rate, digestion, and glandular activity, usually outside conscious control. The central nervous system (brain and spinal cord) processes information, but voluntary movement is carried out through the somatic division via peripheral nerves. The peripheral nervous system includes nerves outside the CNS and contains both somatic and autonomic divisions, with the somatic division specifically responsible for voluntary movement.
