To #GerrieNel : The fight-or-flight response (also called the fight, flight, freeze, or fawn response [in PTSD], hyperarousal, or the acute stress response) is a physiological reaction that occurs in response to a perceived harmful event, attack, or threat to survival.[1] It was first described by Walter Bradford Cannon.[a][2] His theory states that animals react to threats with a general discharge of the sympathetic nervous system, priming the animal for fighting or fleeing.[3] More specifically, the adrenal medulla produces a hormonal cascade that results in the secretion of catecholamines, especially.[4]
