What is the name of the subdivision of the peripheral nervous system that regulates involuntary functions of internal organs?

• A. Central nervous system
• B. Autonomic nervous system
• C. Ganglion nervous system
• D. Neuronal nervous system

Answer: (B)

The autonomic nervous system is the part of the peripheral nervous system that handles involuntary control of internal organs, glands, and smooth muscle. It operates without conscious input to manage essential functions like heart rate, digestion, respiratory rate, sweating, and pupil size. It works through two main branches that often have opposite effects: the sympathetic division prepares the body for action by increasing heart rate and redirecting blood flow, while the parasympathetic division promotes conservation of energy and activities like digestion and resting states. Some descriptions also include the enteric nervous system as part of this network because it coordinates gut function, but the core idea remains that autonomic control governs internal, automatic processes. The other options don’t describe this subdivision: the central nervous system comprises the brain and spinal cord; terms like ganglion nervous system or neuronal nervous system aren’t standard classifications for this function.
