Fight Or Flight Response-The Body's Automative Force

There are three different theories that are used when talking about how we react to stress through the physiological aspect or the psychological aspect. The first is part of the physiological aspect of stress called the Cannon Fight or Flight theory which was proposed in 1914. Fight or Flight response is a physiological stress response that evolved to help organisms to survive immediate danger. The theory states that when an organism, human being or animal, faces imminent danger (acute stressor) the body arouses quickly and is ready to act via two different systems. They are the sympathetic nervous system and the endocrine system. The sympathetic nervous system stimulates the adrenal medulla which is part of the endocrine system and is the region that produces the hormones such as adrenaline and noradrenaline. These hormones increase heart rate, blood flow, and glucose levels to prepare the body for an emergency. This response from the body suggests that the body knows how to protect itself and reach homeostasis. These two systems work together to either fight against the danger or flight away from the danger. Lord, King and Pfister in 1976 studied the Fight or Flight response in animals through a very unethical study. They administered chemicals on male hooded Wistar rats which inhibited the neurotransmitters from functioning normally. This made it very difficult for the rats to escape an electric shock. The results of the study suggest that the Flight or Fight response

When put under stress, both humans and baboons have cortisol and adrenaline found in their blood. These hormones are critical for survival, and other physical changes in the body such as a racing heart, increased blood pressure, and quickly responding muscles are all present when the body is put under stress. However, in regard to humans, these same physical responses can occur when the body is not in a life in death situation. Instead, it is common for psychological stresses such as public speaking, taking a test, paying taxes, or driving a vehicle to invoke the same physiological responses as someone in a critical situation. This can be unhealthy for the human body, as many people can get worked up over multiple stressors in one day,

Fear is a powerful human emotion. It can make you do things you wouldn’t normally do, like risk taking and bad choices. Fear can spike your adrenaline. For example if someone was to lift a car off a run over child, that would be caused by adrenaline, which is caused by fear. According to several studies done by physicians

In Prospero 's case in Masque of the Red Death Prince Prospero, was faced with the threat of survival, surviving the Red Death, a plague sweeping his kingdom killing all it comes into contact with. 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 effects of these two systems are the fight-or-flight response.When the hypothalamus tells the sympathetic nervous system to kick into gear, the overall effect is that the body speeds up, tenses up and becomes generally very alert. If there 's a burglar at the door, you 're going to have to take action fast. The sympathetic nervous system sends out impulses to glands and smooth muscles and tells the adrenal medulla to release epinephrine and norepinephrine into the bloodstream. These "stress hormones" cause several changes in the body, including an increase in heart rate and blood pressure.At the same time, the hypothalamus releases corticotropin-releasing factor into the pituitary gland, activating the adrenal-cortical system. The pituitary gland secretes the hormone ACTH (adrenocorticotropic hormone). ACTH moves through the bloodstream and ultimately arrives at the adrenal cortex, where it activates the release of approximately thirty different

Humans have innate primitive fears that have been preserved through the phylogenetic tree. The "fight or flight response" is the body's automatic response that prepares the body to fight the perceived attack, harm or threat or flee the situation. Both fight or flight mechanisms are actions taken to ensure survival and are decisions made when the specific situation had been analyzed. The person who is in a situation where a tarantula is placed near their foot experiences some sort of fear and the emotional responses they have are due to neural activity and this experiment attempts to pinpoint where these responses emanate from. Only recently, functional neuroimaging or fMRIs have been used to reveal changes in brain activity when the subject experiences some sort of stimulation and provides information about the anatomical networks involved in defensive reactions to fear,

These defenses are real, if not primitive in nature (fight or flight), and are a necessary part to protect our minds in dealing with stress. It is important that we hone our abilities to protect ourselves because it is believed that our inner strengths and resources that we have learned are thought to be the most effective in dealing with stress in today’s world.

In his article “Your Caveman Brain: Running from Predators at Work”, Manie Bosman claims that the human brains have the better performance when people are in a dangerous situation. The author demonstrates the fear of threat when a person meets a lioness and suddenly starts to run, by emphasizing that the main goal of people brain is to survive. While noticing lioness, which represents deadly threat, the brain produces hormones, which accelerates the blood flow and strengthens muscles. This process makes people run faster without thinking in order to ensure safety. Consequently, Bosman indicates that when a human faces unsafe situations he accomplishes tasks in a better way. Moreover, the author mentions that the brain reacts not only

There are a wide variety of responses that people may have such as fight, fly, or freeze. When suddenly startled, people may raise their arms in protective pose, or duck to avoid a perceived object. Some people will immediately attack, some will jump back, while others may drop whatever they are

Flight-or-flight response is marked by physical changes which include both nervous and endocrine changes. The two components of the flight-or-flight response are the neural response and the hormonal response. The neural response is responsible for communicating with smooth muscles via neural connections, while the hormonal response is responsible for releasing adrenaline, noradrenaline, and cortisol into the bloodstream. Both the neural response and the hormonal response make the body stranger, more aware, and faster when it comes to stressful and dangerous

Physiological responses, is a specific changes in how the body is functioning cased by nervous system when facing a specific emotion ; physiological responses is easy to measure because scientists have developed special tools to measure them; heart rate, sweating, blood pressure, or realising adrenaline in bold , is one of many measurement attributes used to measure physiological responses , research proved that people have similar internal responses to the same emotion, regardless of their age, race, or gender , for example human body release adrenaline when people are under stress; this hormone helps prepare to smoothing called the "fight or flight" reaction ,which mean the body preparing to either run away or fight; research shows that

One of the oldest forms of survival is the fight or flight response. Numerous examples of outrageous feats performed by people can be found, but the most pure form can be found in those who still use it daily, and actually use it for survival. Animals utilize their fight or flight response to survive in nature, where a delay or lapse in judgement could result in their death.

When faced with the unknown the human instinct for survival gives us only two options, fight or flight.

Fear can create an instinctual response to perceived danger. A good example is of the time my husband and I were alone on a long hike in the jungles of Belize and came upon a fer-de-lance snake that would most likely have killed us with its bite. Without any time passing, my instinct of fight or flight emerged and I pushed my husband out of the way, telling him to run as I did. Also, in an instinctual state of fear, someone can perform tasks they did not think were possible such as being able to lift a

Defense mechanisms are ways that we are able to protect ourselves from feelings of guilt and anxiety. For example, in my case, I have always continue to struggled with test taking, as well as, writing papers for my classes, this cause my anxiety levels to rise. I would say that, my defense mechanisms would be Rationalization, which is defined as “the cognitive distortion of the facts to make event or impulse less threatening” (McLeod, 2006). How I would apply this, is to make sure that I have ample time to complete my assignment, this allows me time to step away when I being to have feelings of anxiety.

Fear is a normal and an important human reaction to something dangerous, it keeps one out of danger, because fear is disliked and one tries ones best to avoid the object or situation of fear. It causes physical changes known as fight-or-flight reaction, which causes blood pressure to increase and the heart rate to speed up to pump blood to the large muscles used to run away, to balance this the human body has sweat glands which produce perspiration to cool the body.
