A term introduced by the US physiologist Walter Bradford Cannon — , and popularized in his book Bodily Changes in Pain, Hunger, Fear and Rage , for the syndrome of physiological responses of an organism confronted with a situation that evokes fear, pain, or anger, such responses being mobilized by the secretion of adrenalin epinephrine from the adrenal medulla, preparing the organism to fight or to flee. It includes increased blood pressure, accelerated heart rate, deepened respiration, increased sweating, dilation of the pupils, diversion of blood flow from the digestive tract to the skeletal muscles and cessation of digestive processes, release of sugar from reserves in the liver, and closure of the sphincter of the bladder, leading to retention of urine.

Fight-or-flight response

Doctor Daniel Pine introduces the fight-or-flight response, which is a common mechanism in mammals in response to a threat. It prepares the body to either run away or fight the threat. So, we talked a little bit about anxiety as a bunch of different responses to danger and one of the interesting things about anxiety is that probably because, for our ancestors certain kinds of responses were adaptive, we see a lot of similarities in terms of how different kinds of mammals respond to danger. Nonhuman primates, humans, and rodents all have similar kinds of responses when they are confronted by danger. So for some kinds of dangers, all these organisms produce certain changes in the body that prepare the body to cope with danger and one of these sets of responses is what is called the fight-or-flight response. If running away is not an option then the other option is to fight.

Fight-or-flight response , response to an acute threat to survival that is marked by physical changes, including nervous and endocrine changes, that prepare a human or an animal to react or to retreat. The functions of this response were first described in the early s by American neurologist and physiologist Walter Bradford Cannon. When a threat is perceived, the sympathetic nerve fibres of the autonomic nervous system are activated. This leads to the release of certain hormones from the endocrine system. In physiological terms, a major action of these hormones is to initiate a rapid, generalized response.

fight-or-flight response

The fight-or-flight response also called hyperarousal or the acute stress response is a physiological reaction that occurs in response to a perceived harmful event , attack , or threat to survival. This response is recognised as the first stage of the general adaptation syndrome that regulates stress responses among vertebrates and other organisms. The autonomic nervous system is a control system that acts largely unconsciously and regulates heart rate , digestion , respiratory rate , pupillary response , urination , and sexual arousal. This system is the primary mechanism in control of the fight-or-flight response and its role is mediated by two different components: the sympathetic nervous system and the parasympathetic nervous system. The sympathetic nervous system originates in the spinal cord and its main function is to activate the physiological changes that occur during the fight-or-flight response.
