Perceived threats trigger the 'fight or flight' response—that sequential process that prepares you either to put up a fight to defend your life—the fight part, of course—or to scramble and get away as quickly as possible, also in defense of your life—the flight part. Stress and the fight-or-flight mechanism it triggers could cause prostate cancer experts discovered that the part of the nervous system responsible for fight-or-flight fuels the early phases of . Mechanism of stress and stress response: the hypothalmic-pituitary-adrenal (hpa) axis is an endocrine cascade that mediates several aspects of physiological stress, including responses to acute stressors (ie, fight-or-flight response) but it also causes chronic stress. Cortisol (along with its partner epinephrine) is best known for its involvement in the “fight-or-flight” response and temporary increase in energy production, at the expense of processes that are not required for immediate survival.

What is the fight or flight response the flight or fight response, also called the acute stress response was first described by walter cannon in the 1920s as a theory that animals react to threats with a general discharge of the sympathetic nervous system. Post traumatic stress disorder medical or any other kind of trauma, your body responds by activating your basic survival mechanism, the fight-or-flight response. The beneficial effects of short-term stress make sense because the fight-or-flight stress response is nature’s fundamental survival mechanism without this response a lion has no chance of catching a gazelle and eating to live another day. The fight or flight mechanism is a series of rapidly occurring reactions, for the most part in your brain, nerves and glands – so rapid that it happens before your conscious mind can grapple with the danger at hand.

Stressed or stressed out: what is the difference tend-and- befriend,” not “fight or flight of defence mechanisms, it is the stress mediators . Understanding the physiological mechanism of the fight or flight response can provide people a sense that the machinery of the body can be manipulated in a healthy, adaptive way to respond to stress. The fight-or-flight response is also known as the acute stress response essentially, the response prepares the body to either fight or flee the threat it is also important to note that the response can be triggered due to both real and imaginary threats. Cortisol is released in response to fear or stress by the adrenal glands as part of the fight-or-flight mechanism the fight-or-flight mechanism is part of the general adaptation syndrome defined .

This combination of reactions to stress is also known as the fight-or-flight response because it evolved as a survival mechanism, enabling people and other mammals to react quickly to life-threatening situations. The stress responses, fight, flight, or freeze, help us in situations where we perceive physical or mental threat in the above situations, we see the physical symptoms of stress as well as . The fight-or-flight response, also known as the acute stress response, refers to a physiological reaction that occurs in the presence of something that is terrifying, either mentally or physically. This is the fight-or-flight response originally described by cannon 17 passive coping strategies, such as immobilization or freezing, are usually elicited when threat is inescapable, and are usually characterized by autonomic inhibition (hypotension, bradychardia), and a more pronounced increase in the neuroendocrine response (activation of . The 'flight or fight' response the ‘fight or flight response’ is our body’s own protective response to danger and, in essence, it is a mechanism designed to protect us, and not as it feels, destroy us.

Stress and the fight or flight mechanism

The body-mind connection of stress reactions to stress what is the “fight or flight” response about the body mechanisms that cause physiological stress . The fight-or-flight response (also called hyperarousal, or the acute stress response) is a physiological reaction that occurs in response to a perceived , it’s also part of when you freeze up out of fear or stressharmful event, attack, or threat to survival. Fight-or-flight response (in humans) the fight-or-flight response is the first-line physiological mechanism for giving an animal its best chance for survival from: encyclopedia of animal behavior , 2010. The ‘fight or flight response’ was a term first coined in 1915 by dr walter b cannon, and is also known as the ‘acute stress response’ or ‘hyperarousal’ it is an in-built self-preservation mechanism that is made up of a series of neuro, chemical, and hormonal processes that prepare our bodies to effectively respond to threats in .

To produce the fight-or-flight response, the hypothalamus activates two systems: the sympathetic nervous system and the adrenal-cortical system the sympathetic nervous system uses nerve pathways to initiate reactions in the body, and the adrenal-cortical system uses the bloodstream the combined . This combination of reactions to stress is also known as the fight-or-flight response because it evolved as a survival mechanism, enabling people and other mammals to react quickly to life- threatening situations. The fight-or-flight response is a stress reaction that likely evolved out of the survival needs of our early ancestors living with the daily dangers of the time to demonstrate, imagine you’re a prehistoric cave dweller relaxing one evening and enjoying the daily catch.

The fight or flight response (seyle, 1976), however, was only the first in a series of neurological and physiological reactions to stress (bernard & krupat, 1994 nairne, 2009) two mechanisms work in tandem to activate the fight or flight response, the fast acting nervous system and the longer lasting endocrine system (nairne, 2009).
