What controls the fight-or-flight response as a physiological reaction to a threat

Question

Quizplus · Accepted Answer

The fight-or-flight response is controlled by the autonomic nervous system, which includes the sympathetic and parasympathetic nervous systems. When a threat is perceived, the sympathetic nervous system triggers the release of adrenaline and other stress hormones, which prepare the body to fight or flee. These physiological changes include increased heart rate, blood pressure, and respiration, as well as dilated pupils, increased sweating, and slowed digestion. The parasympathetic nervous system helps to restore the body to its resting state once the threat has passed.
