This stimulis is unexpected, highly dangerous and threatening to the 2 individuals. According to Selye ‘Response based stress’ is the body’s response to noxious or aversive stimuli http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2560943/?page=1 , therefore the individuals who were affected by the militant attacks would show symptoms of the early stages of acute stress disorder. The body’s immediate response to stress is implemented by the physconeruoimmunological interactions with the General adaption theory established by Hans Selye. ** stress affects homeostasis

In this situation the sympathetic nervous system (SNS) would dominate the parasympathetic system due to the vigorous physical activity that would be required, and the boost in ATP (Adenosine Triphosphate). This system allows the individual to reduce bodily functions require high amounts of energy such as the gastrointestinal tract, the system relaxes the muscles along the track and diverts the energy. It also has a long lasting effect as the axons that are activated in this system as they have the ability to activate many tissue simultaneously. http://medical-dictionary.thefreedictionary.com/general+adaptation+syndrome
The second stage of the stress response is restistance. The body begins to recover from the intensity of the alarm stage. It is initiated by the hypothalamic hormones and is a longer lasting response. Corticotrophin releasing hormone helps in the stimulation of the release of cortisal. The cortisal then stimulates the gluconegensis through the liver to break down other products into amenoacids, fatty acids and glucose to produce ATP to repair damaged cells.
Impaired immune
What he observed was adrenaline and glucocorticoids dictate the stress response. The physiological changes to the body during the stress response are the lungs work overtime to deliver oxygen to the bloodstream, and the heart races to pump oxygen throughout the body so muscles respond instantly. The blood pressure needs to go up to deliver energy. The body will turn off anything that is not essential at that moment. Examples
The biological purpose of the stress response is to help the body to survive either some sort of attack or a serious illness like a stroke or heart attack. During the stress response glucocorticoids divert the bodies energy to the areas necessary for survival like the muscles and the brain and it shuts down the areas that are not necessary for survival like the digestive and immune systems (Sopolsky, 2009). Chronic Stress in this context, is to experience this physical effect on regular or long term basis. This has become a public health issue for humans because we experience this chronic biological response on a too frequent a basis for psychological reasons (Stress, 2008).
Acute Stress Disorder (also known as ASD) is a trauma or stressor related disorder that is diagnosed in an individual within 2 days to one month after a traumatic event has occurred. This disorder can be a sign for posttraumatic stress disorder (also known as PTSD), but PTSD cannot be claimed in a patient until four weeks after an event has happened.
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
Stress has a huge impact on the immune system. The immune system is interconnected. For example the immune, nervous, and endocrine system is linked through specialized communication pathways involving hormones, neurotransmitters, neuropeptides, and immune cell productions. Stress reactions can directly affect the various response systems and how they handle the neuroendocrine-products. This stress reaction directly affects the hypothalamus and pituitary peptides through the sympathetic branch of the autonomic nervous system. Some of these stressors might be life events, anxiety, and excitements.
Keeping a stress journal has opened my eyes to the opportunities that I have around me Everyday. I wake up and ultimately do the same thing day in and day out; the only difference is the stress I encounter. It is hard to believe, it took an assignment to open my eyes about the great things in my life. Reading over my stress journal analysis, I have learned to care for the people in my life and I have notice I have a lot of hate and angry built inside. In my life there many stressors, the main one I have notice through tis project is angry.
(2.) Acute stress disorder is characterized by panic, mental confusion, dissociation, severe insomnia, suspiciousness, and being unable to manage even basic self-care, work, and relationship activities.
Normal stress response occurs when healthy adults who have been exposed to a single discrete traumatic event in adulthood experience intense bad memories, emotional numbing, feelings of unreality, being cut off from relationships or bodily tension and distress. Acute stress disorder is noted by panic reactions, mental confusion dissociation, severe insomnia, suspiciousness, and being unable to manage in self-care, work, and in relationship activities. Uncomplicated PTSD persistent reexperiencing of traumatic event, avoidance of stimuli
Stress and anxiety in the average college student. Selye (1936) defined stress as “the non-specific response of the body to any demand for change” (The American Institute of Stress, 2017). Stress can lead to feelings of anxiety. Anxiety is a normal part of life, but can be considered a type of worry or fear that can inhibit everyday life. College students show higher stress/anxiety than average individuals. Major sources of stress are from new responsibilities, campus living, money issues, and classwork (Ross, Niebling, & Heckert, 1999). There have been a number of studies circled around how stress can affect college students. Females and males show differences in anxiety/stress in college. (Misra and McKean (2000)) found that females
The General Adaptation Syndrome (GAS) can measure physiological response to stress. It starts with the alarm phase, where you recognize the stimulus and decide you need to confront the stress that you have. This activates the sympathetic nervous system and deactivates the parasympathetic nervous system. It releases a stress hormone that is a biological marker of stress. Once you have evaluated the situation and decided what to do, you enter the resistance phase, in which the body starts to address the stimulus and tries to go into
Psychological and physical well-being and the overall quality of life are under a constant threat of stress and thus, psychological and medical sciences have long been concerned with studying stress response. Cox (1979) claimed that because of the poor understanding and defining it, the concept of stress tends to be rather elusive. The term, “stress”, commonly describes any physchological or physical alteration that deranges the organism’s homeostasis (or balance). This essay reviews some of the biological factors involved in stress and it has been organized in the following way. The paper begins by briefly introducing the concept of stress. It will then go on to discus and describe the automatic response (fight or flight reaction),
Psychological stress is a result of many factors and should be dealt with very carefully. Stress can be defined as “An excess of demand made upon the adaptive capabilities of the mind and body”.(Joseph 1). Another way of putting it, is that there are some things that put certain demands on us. The effects of stress should not be limited to unpleasant emotional states. Many studies have concluded that the effects on our physical health from stress can be extremely detrimental. These adverse physical effects include heart disease and formations of cancer. There are also some societal issues that psychological stress can hamper.
Stress is a state of emotional or mental tension or strain resulting from very demanding and adverse circumstances in an individual’s life. The term general adaptation syndrome (GAS) is used in describing the long-term and short-term reactions to stress through its three stages that explain an individual’s experience with stress. The alarm reaction stage is the initial stage where an individual reacts immediately to a stressor exhibiting a "fight or flight" response that prepares one’s body for any physical activity. This stage may however, result in decreased immune system effectiveness, making individuals more prone to an illness during this phase. The resistance is the second stage where f stress continues one’s the body forms an adaptation to the stressors with different levels of changes taking place to reduce the effectors stress. The exhaustion stage is the third one where one’s body resistance resistance to stress may gradually reduce or collapse quickly meaning that one’s immune system to resisting diseases may be almost eliminated.
Long-term activation of this stress-response system can lead to the disruption of almost all of the body’s processes. If this happens, the individual has an increased risk of developing numerous health problems. So, to prevent this from happening, the problem must be nipped in the bud.
Stress affects the body in many different ways. Many doctors estimate that stress is involved in more than half of all illnesses (Sapolsky, 21). Stress may cause or prolong an illness or increase its severity. Epinephrine and norepinephrine are hormones that are released during a stress reaction that affect organs throughout the body. As a result from the hormones being secreted, the heart begins to beat more rapidly, muscle tension increases, blood pressure raises, and heavy breathing may occur. This reaction is known as the fight-or-flight response. The fight-or-flight response energizes the body to either confront or flee from a threat. Heredity, learning, and injuries all play a role in determining where or when a stress related illness may occur in a particular individual (Sapolsky, 22).
