The parasympathetic nervous system is best described as which of the following?

• A. Rest-and-digest state that helps return the body to equilibrium
• B. Fight-or-flight state that prepares the body for action
• C. Central nervous system
• D. Somatic nervous system

Answer: (A)

The question is testing that the parasympathetic nervous system is the rest-and-digest part of the autonomic nervous system, focused on restoring balance after stress. It promotes energy conservation and recovery by slowing the heart rate, increasing digestive activity, and supporting repair processes. This system counteracts the sympathetic “fight-or-flight” response, which prepares the body for action. It’s not the central nervous system (which includes the brain and spinal cord) and not the somatic nervous system (which controls voluntary muscles). After intense activity, parasympathetic activity helps the body return toward baseline and supports recovery.
