The Fight Or Flight Response

In the wild, animals need fear in order to survive in harsh conditions. For example, in Africa, zebras are often hunted by large cats like lions. If they didn’t fear lions than they would not flee from them and they would most likely go extinct. However, due to the fact that they have that fear of being eaten, their instincts tell them to flee the scene and get away from the dangers. This has allowed them to survive for thousands of years even though they’ve been hunted for the span of

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

The Holocaust: A genocide in which six million Jews died, still remembered today as the single most grotesque massacre in human history. For most, the concept of Hitler’s rise to power, the building of his strength, and the process by which his orders were carried out remains an unimaginable concept. In the mind, laws of morality don’t bend. In looking at the Holocaust, one has to wonder how so many managed to break the rules of humanity so quickly. The easiest answer questions the existence of ethical laws at all. Although others consider the vast majority who did not fall victim to Hitler’s power to simply be better people, a consensus of Germany pre-war reveals that they were not miniature bigots.

Hayslip, Pruett, and Caballero (2015) construe the grief responses of young adults who have lost parents, and suggest that young adults were burdened more so than middle-aged adults. The authors propose that many young adults lack the support system that is so fundamental in coping with loss, making their grieving process more problematic. Instinctive coping responses in young adults when grieving, specifically the loss of a parent, include anger, insomnia, losing interest in endeavours, and trouble working with others. A study within this article found young adults feel more animosity towards the deceased, and more shock.

Under conditions of stress, the nervous system, via the SAM (sympathetic-adrenal-medullary) and HPA (hypothalamic-anterior pituitary-adrenal cortex) systems, produces neurotransmitters and hormones (such as cortisol and catecholamines) that bind to receptors on immune system cells;

There are numerous neurological changes occurring in our body as a response to fear. Specifically, two pathways are activated: the sympathetic nervous system and the hypothalamic- pituitary- adrenal pathway. In a similar way, both pathways commence by receiving messages from the hypothalamus, an area of the brain responsible for many functions in the body, such as activating the autonomic nervous system, controlling different organs, and managing physiological functions. If the hypothalamus emits messages that we are facing a threatening situation, it will release different chemicals to either the sympathetic nervous system and the hypothalamic- pituitary- adrenal pathway. This sympathetic nervous system are “nerve fibers of the autonomic

According to Dr. Jaime De La Torre , there are a number of primary survival attitudes in animals and in humans as well. When an animal feels threatened, its first reaction is to move away from the threat. This avoids pain, danger and energy expenditure. However there are situations in which the escape is not possible, and it is in these cases when the animal becomes aggressive and activates a series of reactions in his body that prepare him for the fight. The aggression provoked by fear is characteristic of animals in danger that feel cornered and with no possibility of escape. As long as the animal feels that it has an opportunity to overcome what threatens it, it will fight against it. It is human nature, and hard wired into our brains to

glucoprivation, and of manifestations of emotional distress. In contrast with the view that the sympathetic nervous and adrenomedullary hormonal systems function as a unit (the ‘sympathoadrenal system’) to maintain homeostasis in emergencies, across a variety of situations adrenaline responses are more closely linked to responses of the hypothalamic‐pituitary‐adrenocortical system than of the sympathetic nervous system. The sympathetic noradrenergic system is active even when the individual is at rest and maintains tonic levels of cardiovascular performance. Adrenoceptors in the membranes of effector cells determine the physiological and metabolic effects of catecholamines. Noradrenaline and adrenaline are catecholamines. Noradrenaline is the

It is normally produced by both the adrenal glands and certain neurons. It is commonly used as a medicine in a number of conditions such as cardiac arrest, anaphylaxis, and superficial bleeding. It plays an important role in the fight-or-flight response by increasing blood flow to muscles, output of the heart, pupil dilation, and blood sugar. The fight-or-flight response is a physiological reaction that occurs in response to a perceived harmful event, attack, or threat to survival. In a stressful situation you feel your heart start racing and your hands start to sweat. This triggers the fight-or-flight response which opens up the adrenal medulla gland in response to your nervous system. Epinephrine is then released into your system to prepare you for danger. It triggers the blood vessels to contract to re-direct blood toward major muscle groups, including the heart and lungs. While this process occurs the ability for ones' body to feel pain decreases and strength and performance increases. Which is why some people are able to keep running or moving even after they have been injured. After the situation has been dealt with the adrenaline will last up to an

Epinephrine, also known as adrenaline, is secreted through the adrenal glands in the medulla, and is responsible for the fight or flight response in humans. When injected into the body, epinephrine attaches directly to the alpha-1 and beta-1 receptors. Alpha-1 receptors, also known as vasopressors, are responsible for the constriction of the blood vessels. Beta-1 receptors are responsible for the cardiac output of the heart as well as the increase in heart rate.

Adrenaline is a hormone that the adrenal glands produce. They are produced during times of stress or excitement. This is a powerful hormone that is a part of the body's flight or fight response. It works by diluting air passages, contracting blood vessels and stimulating the heart. This helps supply the lungs with more oxygen and increase blood flow to the muscles.

People often do the unimaginable in order to survive the dangers around them. To me, surviving is trying to stay alive by eating, drinking, and finding shelter. The fight or flight statement also means to survive because it is how we perceive harmful events. Some of these events can be an attack, or threat to survival. Surviving doesn't always have to be through harmful ways, you can also survive mentally. In other words, stay strong, have hope, believe you can, and have faith no matter how difficult it gets. Surviving skills can be inherited, such as the F or F, but people all over the world have inherited different ways to survive.

When I was about to ask for help, I thought that my teacher was going to judge the information I was disclosing. I was resistant because I did not want to feel judged, and I had this horrible feeling that she was going to look down on me. “Students may realize that allowing oneself to fully acknowledge the injustice and suffering in the world may lead to disturbing emotions. Resistance can be a way to shield themselves from painful feelings of guilt, shame, sadness, anger, and powerlessness. Therefore, instead of being open to new information and exploitation, they may choose, consciously or unconsciously, to shut down or push away” (Goodman, 2011, pg. 60). There I was grappling with the idea of whether I should even ask for help. I did not want to stir up emotions that I did not have to cope with for most of my life.

Fear is a natural instinct for survival. Without it, people would always get into uncomfortable and sometimes harmful or fatal situations. Instead, they unconsciously weigh the odds of survival and decide whether they should fight or run. Just like humans, animals also have an instinct of fear. Animals either flee or use defense mechanisms when they are afraid. Defense mechanisms include camouflage, mechanical defenses (quills, teeth, shells, claws), and chemical defenses (sprays, poison). Opossums play dead and release on odor, deer run, cats

Fight or flight is a response to adrenaline. Adrenaline is a protein created in your cells as a reaction to a stimulant. This stimulant can be someone jumping at you from behind a door, or it can be quick decision making. Your brain responds accordingly to the stimulus. If
