Extract of sample "The Physiology Of The Fear Response"

Download file to see previous pages When an individual experiences fear, there is an automatic fight or flight response that is stimulated in him or her. The body responds to the sensation of fear with an increase heart rate, faster breathing and muscle tension which results in the body breaking out into shaking or trembling. This allows the individual experiencing the fear to either stay on and fight or to run away from the source of the danger and fear causing stimulus. However, this initial physiological response is followed by a deeper psychological assessment of the fear generating circumstances, during which time the individual becomes conscious of feeling afraid.
When an individual receives a visual or other kind of stimulus that indicates a potentially dangerous situation, neurons in the body send a signal directly to the amygdale, a specific region of the brain. The amygdala picks up on stimuli that appear dangerous and sends out powerful panic signals which produce the concomitant physical responses such as increased heart rate, shaking and trembling of the body and sweating. ...Download file to see next pagesRead More

Fear

...Section/# Fears According to the piece by Phil Barker, the main determinant for fear within the individual is threat to existing structure, tradition, or the status quo. As a function of this fear, the individual is oftentimes coaxed into a form of action and response that they might otherwise engage in if they did not feel threatened that some core identity was being threatened. This understanding of identity formation and the ways that the individual can reject foreign ideas based upon this is an exceptional means of understanding the way that fear, anger, rejection, and oftentimes violence can result from something as simple as a primal and innate...

About fear

...About Fear Phil Baker describes fear as an unpleasant strong emotion occurring as a result of an awareness or anticipation of danger. Fear is a natural feeling that helps people in recognizing and responding to dangerous threats and situations. However, healthy fear that plays a protective implication has the potential to develop into pathological (unhealthy) fear that in some instances leads to exaggerated, aggressive and violent behavior. Dr. Ivan Kos presents a number of diverse stages of fear. The first is real fear that is based on life experiences and states. If something or someone causes hurt to an individual,...

...? Causes of diabetes Research proposal Insert Grade Introduction Indeed, diabetes has become a major global crisis due to its effects and scale of prevalence. It has led to an unproductive society that directly impacts its growth. Its physiological aspect is that many studies show that it majorly arises from the lifestyles that people lead (Dijk, 2012). The outcome of diabetes is profound in that it also affects the physiological well-being of a person. Dijk (2012) states that a lot of people suffer from type 2 diabetes which has been found to be on the rise with the rise in obesity. Study also shows that with its faster economic growth, Asia has become the epicenter of the disease. According to Struijs...

Fear

...of dying suddenly and violently I am afraid of dying alone. Themes and Clusters Identified: In examining my responses, I perceive positives and negatives in the clusters. Looking at what I deem to be positive outcomes in what I do and do not fear, it suggests to me that I value people and will treat them with love, loyalty and duty. I am not afraid of making those I love unhappy, because this is not a natural way for me to be. This belief is supported by my fear of abandoning people who depend on me, of losing those I care about and of not having time to make amends if I have hurt them in any way. Or indeed, if I have wronged anyone, I want to make it right. This shows me to...

...and systemic vascular resistance rise afterload as well as ventricular dilatation or aortic valve stenosis. Question 5 Discuss the role of the Frank-Starling mechanism in control of the cardiac output of the heart. (10) The Frank-Starling mechanism is the capability of increasing of heart muscle contraction and stroke volume in response to increased venous return. Increased venous return increases end-diastolic volume and heart preload. Increased heart preload is related to the stretching of the cardiomyocytes. Myocyte stretching increases the length of sarcomeres and the force of ejection. This process caused length-dependent activation. Question 6 Give a brief description of the mechanisms involved in the control of...

...Skeletal System Essay DESCRIBE THE DEVELOPMENT AND GROWTH OF BONES Ossification or osteogenesis begins towards the end of 8th week of gestation. All bones begin as mesenchymal condensations during the embryonic period. The fibrous condensations ossify into the membrane or dermal bones and the cellular condensations ossify in to hyaline cartilages (Gardner, 856-862). Thus, the skeletal pattern is formed in cartilage and connective tissue membranes. From here, bone development continues throughout adulthood. The 3 cell types involved in the development, growth and remodeling of bones are osteoblasts, osteocytes and osteoclasts. While osteoblasts are bone-forming cells, osteocytes are mature bone cells and osteoclasts break down... System Essay...

...of gases you inhale during normal breathing. However, 6% of oxygen is breathed out together with carbon dioxide and other waste products. (Science Fair 2003: Does Exercise Affect the Amount of Carbon Dioxide Exhaled, 2003) During exercise, the body needs more energy which is provided to it through the chemical reaction of oxygen and glucose. This, in turn, means that during exercise, the body needs more oxygen. This extra demand in oxygen is provided through deeper and faster breathing. However, it is important to note that the respiration of the body is controlled by carbon dioxide and not oxygen. During exercise, the production of carbon dioxide in the body is increased. A part of the brain, known as medulla, is...

...Joan Wedgworth, fear essay Lynda Nance English 101 February 26, Arachnophobia: Not Just a Movie There was a time as a little girl that I was fearless, afraid of nothing, not the dark not going to school, nothing. I remember always wanting to try new things, go on the big rides at the amusement parks that I could not even go on yet because I was too young. Looking back on it now I see that it was a child’s naiveté and the fortunate 8 years growing up that had not resulted in any traumatic experiences, yet. I am not certain that most fears develop in childhood; perhaps some are learned later in life through one’s experience, and yes I have those too. However, I can now attest that my most terrifying...

...Physiology behind Pulse Rate, Temperature, Respiration and Control Mechanisms of Peripheral Resistance. Submission: Physiology behind Pulse Rate, Temperature, Respiration and Control Mechanisms of Peripheral Heat has to be related to the skin’s surface in order to maintain a constant body temperature. After the evaporation, the cooled blood returns to the core of the body this regulating the temperature. Blood flowing through the dermis is regulated when one’s body heat is stable depending on the changes in ambient temperature. This is to ensure that differences in temperature between the environment and the skin remain constant thus preventing heat loss and attaining a constant temperature (Yagiela,...
