Which role does the somatic nervous system play during exercise?

• A. Controls involuntary hormones
• B. Regulates digestion
• C. Manages voluntary movements
• D. Facilitates nutrient absorption

Answer: (C)

The somatic nervous system is primarily responsible for managing voluntary movements, which is crucial during physical activities such as exercise. It connects the central nervous system to skeletal muscles, allowing individuals to perform deliberate actions like running, jumping, and lifting weights. When you exercise, the brain sends signals through the somatic nervous system to activate the muscles required for these movements, coordinating actions based on conscious intent.

In contrast, the other roles mentioned are associated with different systems or functions. For instance, the regulation of digestion and nutrient absorption falls under the autonomic nervous system, which operates involuntarily. Hormonal control also typically occurs through the endocrine system rather than the somatic nervous system. Thus, option C accurately represents the specific function of the somatic nervous system during exercise, highlighting its role in muscle control and voluntary motor functions.
