What does the somatic nervous system provide?

• A. Autonomic control of viscera.
• B. Conscious perception of the environment and voluntary movement.
• C. Reflex arcs only.
• D. Hormonal regulation.

Answer: (B)

The somatic nervous system is responsible for conscious perception from the body and for voluntary control of skeletal muscles. It carries sensory information from skin, joints, and muscles to the brain and spinal cord, and it sends motor commands from the CNS to skeletal muscles so you can move deliberately. This system underpins your awareness of the environment and your purposeful actions. It does not regulate visceral organs (that’s the autonomic system) and it isn’t about hormonal control (endocrine), and while reflexes can involve somatic pathways, the defining function is conscious perception and voluntary movement.
