Which system includes the sympathetic and parasympathetic divisions that regulate involuntary functions?

• A. Autonomic Nervous System
• B. Somatic Nervous System
• C. Central Nervous System
• D. Enteric Nervous System

Answer: (A)

Control of involuntary functions across the body is handled by the autonomic nervous system. This system operates largely outside conscious control and manages processes like heart rate, digestion, breathing, and pupil dilation. It has two major branches that balance each other: the sympathetic division prepares the body for action, increasing alertness and energy; the parasympathetic division promotes rest, digestion, and energy conservation. Together they regulate your body's automatic functions without you thinking about it. The somatic nervous system handles voluntary muscle movements; the central nervous system comprises the brain and spinal cord and coordinates many activities but doesn’t describe the dual involuntary regulation by these two branches; the enteric nervous system governs gut-specific activities and can function independently, but the overarching system that encompasses the sympathetic and parasympathetic divisions is the autonomic nervous system.
