Fight-or-Flight Response

From Openwaterpedia
(Redirected from Acute stress response)

noun - The fight-or-flight response (also called the fight-or-flight-or-freeze response, hyperarousal, or the acute stress response) is a physiological reaction that occurs in response to a perceived harmful event, attack, or threat to survival. It was first described by Walter Bradford Cannon and is activated by the autonomic nervous system, which primes the animal for fighting or fleeing. This response is recognized as the first stage of a general adaptation syndrome that regulates stress responses among vertebrates and other organisms.
