Which division reverses the action of the sympathetic nervous system by slowing down its activity?

• A. Parasympathetic
• B. Sympathetic
• C. Central nervous system
• D. Enteric

Answer: (A)

The tendency of the body to shift from a high-energy, "fight or flight" state to a calm, maintenance state is governed by opposing autonomic divisions. The parasympathetic division acts to conserve energy and promote "rest and digest" activities, which includes slowing the heart rate and stimulating digestion. By counteracting the effects of the sympathetic division, it effectively reverses its heightened activity and returns the body toward a relaxed state. The central nervous system isn’t a direct opposing branch that reverses autonomic actions across the body, and the enteric system is a gut-focused network that functions largely independently of reversing sympathetic activity. The sympathetic division itself increases activity, so it’s not the one reversing it.
