Is the somatic nervous system sensory or motor or both?

• A. sensory
• B. both
• C. motor
• D. neither

Answer: (B)

The somatic nervous system includes both sensory and motor components. It carries sensory information from the skin, muscles, joints, and other somatic receptors to the central nervous system, allowing conscious perception and proprioception. It also transmits motor commands from the central nervous system to skeletal muscles, enabling voluntary movements and reflex actions. So it isn’t limited to sensing or moving alone; it encompasses both pathways. For example, touching a hot surface involves sensory input that informs you of the heat, and a motor response that pulls your hand away. This dual role distinguishes it from the autonomic nervous system, which mainly manages involuntary functions.
