The autonomic nervous system regulates which type of actions?

• A. Voluntary movements
• B. Involuntary body functions
• C. Reflex responses
• D. Perception

Answer: (B)

The autonomic nervous system governs actions we don’t consciously control, keeping our internal system functioning smoothly. It regulates involuntary body functions such as heart rate, digestion, respiratory rate, pupil size, and glandular activity. This automatic control helps maintain homeostasis and adjusts our physiology in response to stress or relaxation through its sympathetic and parasympathetic branches. Voluntary movements are managed by the somatic nervous system, perception involves processing by the brain, and reflexes can be automatic but are not the broad focus of autonomic regulation.
