Which part of the nervous system is primarily responsible for voluntary muscle control?

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

Answer: (C)

The somatic nervous system is primarily responsible for voluntary muscle control. It is a component of the peripheral nervous system and is involved in transmitting sensory information from the body to the central nervous system and sending motor commands from the central nervous system to the skeletal muscles. This allows for conscious movement and actions, such as walking, writing, or playing an instrument. In contrast, the central nervous system, consisting of the brain and spinal cord, processes information, but it is the somatic nervous system that specifically governs the voluntary movements of skeletal muscles. The autonomic nervous system, another part of the peripheral nervous system, regulates involuntary functions such as heart rate and digestion, and does not control voluntary muscle movement. The term "centrifugal nervous system" is not a recognized component in neuroanatomy or neurology related to muscle control. Thus, the correct answer reflects the somatic nervous system's key role in facilitating voluntary muscle actions.
