As Bernard (1961) postulates, all living organisms must have methods of self-protection, whether that means compensating for minor variations in the temperature, fighting off invading organisms, or fleeing from a predator. As organisms became more compound, so did the repertoire of responses that could be used to fend off harm. It seems reasonable that organisms better equipped to guard themselves would have a continued existence and evolutionary advantage over those less equipped. Physiologists and psychologists use the term fight-flight reaction in orientation to this loosely defined constellation of functions.
Basically, fight-flight response is a prototype stress response. It is an energetically intense set of behavioural and physiological changes, undertaken in the interest of maintaining life in the most acutely threatening circumstances. The fight-flight response includes powerful emotional elements and equally powerful exercise-related neuroendocrine and physiological changes. …show more content…
These include (1) anxiety, a sense of apprehension, and the anticipation of physical harm; (2) fear, a stronger form of uneasiness, often felt in the presence of the threat itself; and (3) anger, an outward directed destructive impulse. These emotions, accompanied by neuroendocrine and physiological reactions, motivate adaptive behaviours during threatening circumstances. A primary constituent of all fight-flight situations is that the organism has limited control over the outcome: It is not certain at the outset that serious injury or death can be avoided. In fact, capture, and the helplessness connected with forced immobility are known to be among the most profound of aversive stressors. The tonic immobilization of an experimental animal is therefore used as a highly reproducible and helpful laboratory
