The autonomic nervous system is primarily responsible for which type of control?

• A. Voluntary control
• B. Involuntary control
• C. Respiratory control
• D. Glandular control

Answer: (B)

The autonomic nervous system handles actions that happen without you thinking about them. It regulates activities of internal organs and tissues—heart rate, digestion, pupil size, glandular secretions—so your body functions smoothly without conscious control. This contrasts with voluntary control, which governs your skeletal muscles and movements you choose to make. While you can influence breathing if you focus on it, the autonomic system maintains automatic, ongoing regulation of many functions, making involuntary control the best description of its role.
