Question

Quizplus · Accepted Answer

The sympathetic nervous system is responsible for the "fight or flight" response, which prepares the body for sudden activity and stress by accelerating the heart rate, dilating the pupils, and initiating smooth muscle and glandular responses. The parasympathetic nervous system, on the other hand, helps to restore the body to a calm state after the stressor has passed. The somatic nervous system controls voluntary movements, while the HPA axis is involved in the body's response to long-term stress.
