Fight-or-flight response

The fight-or-flight response is the reaction when a person perceives a threat. This person has now has two physiological options, to stand up to that threat and fight, or to run away (Grohol). To understand what happens during fight or flight, one needs to understand what chemicals and hormones are used during the process. First, the nervous system is broken down into two major systems: Central and Peripheral. The central nervous system consists of the brain and the spinal cord, and deals with emotion and motor skills. Next, the peripheral nervous system is divided into two sub-systems: the somatic nervous system, which regulates voluntary actions, and the autonomic nervous system (ANS), which is linked to involuntary activities. The ANS adjusts internal organ functions.…

You can feel a rush of energy go through your body. Your hands start to shake, you are alert, the energy you have is through the roof. It’s called adrenaline. The hormone secreted by the adrenal glands, especially in conditions of stress, that gives you that extreme rush of energy that makes you feel like you can do almost anything. Most of the cases, when you get an adrenaline rush, are in fight or flight situations. The fight-or-flight response is a physiological reaction that occurs in…

the hazard, but you see no one. Your heart starts racing. You begin to sweat. Your mouth dries and you feel butterflies in your stomach. Your hair stands on end. You feel a surge of energy and in a split second you find yourself running away from the noise. Whether you’re aware of it or not, your body just went through a response known as the fight or flight response also known as the acute stress response. The fight or flight response evolved as a mechanism enabling humans and other mammals…

For example, people with ophidiophobia, the fear of snakes, will get the fight-or-flight feeling when looking at a photograph of a snake. There is no way that the snake in the photo could hurt them, but they are still afraid, making it a phobia. Phobias are sometimes caused by traumatic events causes in childhood. There are three main types of phobias: agoraphobia, social phobia, and specific phobias. Agoraphobia is a fear of places where escape might not be easy or where help might not be…

Introduction Adrenaline refers to a natural stimulant created in the medulla in the adrenal organs. And also partly by certain parts of the central nervous system's neurons. In a few minutes time amid a distressing circumstance, adrenaline is immediately discharged into the blood, sending impulses through the autonomous nervous system to organs to make a particular reaction, for instance the production of sweat and saliva, pupil dilation and heart rate. It is responsible for the human…

quality of trust or confidence in themselves to do so. Overall it leads back to their instincts as a reference in its definition. Instincts come from the word instinctus or better known as an impulse, stating that an organism's biological nature is to make decisions over one another. It's just another tool that the body uses to survive It is pre-programmed into organisms to recognize any potential danger, also known to be the fight or flight response. (Your Gut Feeling Is Way More Than Just A…

them to make extreme decisions. Both of these pieces of literature include examples of physiological changes in humans in order to keep them healthy, emotional contagion amongst the group of characters so as to form a community, and a large focus on the natural fight or flight response when subjected to immense stress. Accordingly, all are adaptations that help the…

evolution and survival of every animal species. In our study, we will focus on vasovagal fainting episodes induced by viewing injections and wounds in persons with Blood-Inject-Injury Type Specific (BIITS) phobia. Reports of fainting reactions to fear-related stimuli are less than 0.1% across all phobias but reported in 100% of BIITS phobia patients (H. Stephan Bracha, 2004). In physiological terms, a BIITS phobia vasovagal fainting response consists of two phases. First there is a brief spike…

quicker and better. However, when stress exceeds a certain point, life can become overwhelming and can result in damaging a person’s health, mood, relationships, and quality of life. Luckily, there are ways to recognize the signs of stress and reduce the damaging effects stress has on the physical dimension of health. Stress is the body’s way of responding to any kind of demand or threat. When an individual feels threatened, the nervous system responds by releasing a flood of stress hormones,…

Stress is defined as “appraised by the person (of a situation) as taxing or exceeding his or her resources and endangering well being, ” (Lazarus & Folkman, 1984) and is commonly regarded as something people experience when they attend hospital. Having a high stress level may impact negatively on communication between patient and staff within the hospital, with communication being defined as “The process of passing information and understanding from one person to another" (Theo Haimann SAY WHAT…
