Which part of the nervous system controls voluntary activities?

• A. Autonomic
• B. Sensory
• C. Central
• D. Somatic

Answer: (D)

The part of the nervous system that controls voluntary activities is the somatic nervous system. This system is responsible for the conscious control of skeletal muscles, which enables individuals to perform voluntary movements such as walking, talking, and other intentional actions. When you decide to move a muscle, the somatic nervous system transmits signals from the brain to the muscles, allowing for precise control over those voluntary actions. In contrast, the autonomic nervous system regulates involuntary functions such as heartbeat, digestion, and breathing, which occur without conscious thought. The sensory nervous system is involved in transmitting sensory information from the body to the brain, helping the brain interpret various stimuli but not in the control of voluntary muscle movements. The central nervous system, which includes the brain and spinal cord, serves as the main control center for processing information and coordinating body functions, but it does not directly control voluntary activities on its own. Thus, the somatic nervous system is the correct choice when discussing the control of voluntary activities.
