GENERAL HISTOLOGY

Detailed explanation-1: -The amygdala triggers a person’s fight-or-flight response. This leads to the release of hormones that prepare the body to fight the source of danger or flee from it. Amygdala hijack occurs when the amygdala activates the fight-or-flight response when there is no serious threat to a person’s safety.

Detailed explanation-2: -Today, however, you’re more likely to experience psychological threats, such as the pressures and stress of modern life, work, and relationships. These emotions, too, can trigger the amygdala’s fight-or-flight response. Anger, aggression, fear, and stress are all common emotional triggers.

Detailed explanation-3: -The amygdala initiates the fight-or-flight response before the cortex has had a chance to overrule it. this cascade of events triggers the release of stress hormones, including epinephrine and cortisol.

Detailed explanation-4: -The fight or flight response is an automatic physiological reaction to an event that is perceived as stressful or frightening. The perception of threat activates the sympathetic nervous system and triggers an acute stress response that prepares the body to fight or flee.

Detailed explanation-5: -If the amygdala perceives a match to the stimulus, i.e., if the record of experiences in the hippocampus tells the amygdala that it is a fight, flight or freeze situation, then the amygdala triggers the HPA (hypothalmic–pituitary–adrenal) axis and “hijacks” or overtakes rational brain function.
