Module 3 - SLP STRESS AND THE IMMUNE RESPONSE (Research Paper Sample)
Module 3 - SLP STRESS AND THE IMMUNE RESPONSE Note: If you have trouble viewing some of the course materials, install Quicktime and the Adobe Shockwave Player, both of which can be downloaded free from the Internet. You must complete your Case 3 assignment before you can proceed with this assignment. In this module's SLP assignment, you will take a break from the anatomy and physiology of stress to analyze the work you have done so far, specifically in your Module 3 Case Assignment. The readings you accomplished for Module 3's Case Assignment are quite new scientific theories that are currently being tested by scientists who are trying to figure out why individuals suffer from behavioral issues such as depression and PTSD. The scientific and medical communities have collected a lot of evidence that stress plays a very big role in not only creating these behaviors, but also perpetuating them. We still have a long way to go and a lot of unanswered questions! By completing Case 3, you have participated in the scientific method. After you view this linked animation, use this diagram as your reference point to complete the following components of this assignment: In which part of the Case Assignment did you address Step 1, “observe and generalize”? Which part of the Case Assignment required you to accomplish Step 2, “formulate a hypothesis”? Did your hypothesis contain information that can be accepted as the absolute truth? If not, what information was missing? (HINT: Think back to the studies about cortisol and PTSD.) Based on the information that was missing from your hypothesis, what could you test in order to obtain more information on the unknown piece? Do a bit of research on the technology available today that could facilitate this test. Examples of new technology include brain imaging, blood chemistry and hormone level tests, CAT scans, MRIs, and DNA mapping. What step of the scientific method does this require? Now that you have some additional information, briefly and in simple terms, describe how you would test the missing information and which step of the scientific method this accomplishes. SLP Assignment Expectations For this SLP assignment, answer all questions using full sentences in paragraph format. For any additional research you are required to do to complete your assignment, please use scholarly references such as a peer reviewed journal article or a government sponsored or university sponsored website. As you read through your sources, take notes from your sources and then write your paper in your own words, describing what you have learned from your research. Direct quotes should be limited and must be designated by quotation marks. Paraphrased ideas must give credit to the original author, for example (Murray, 2014). Direct copying from “homework help” websites will not receive credit. source..
Stress and the Immune Response Name Institution of Affiliation Date Stress and the Immune Response Stressful occasions can cause dysregulation of body immune response in both human and animal immune system. Inquiries in both human and animals raised concern that the adverse effects are significant to health. Thus, research on how stress can impair the body immune are of interest in the health field. Key studies regarding this topic are focused on immune response, the endocrine system, and the central nervous system. Moreover, the researchers attempt to unfold the impact of these interactions on an individual's health. The functioning of the body's immune system can be dysregulated by two pathways, which are the sympathetic adrenal medullary (SAM) and the hypothalamic pituitary adrenal (HPA). The granulocytes, monocytes, and lymphocytes have receptors for catecholamine and cortisol (Knight, 2003). These products can alter the process of cytolysis, the formation of antibodies, secretion of cytokine and proliferation process in the body. For instance, research in vitro where peripheral blood leukocytes were treated with catecholamine resulted in an upsurge in interleukin-10 synthesis and decline in the production of interleukin-12 (Padgett, 2003). If the findings reflect the likely occurrence in an individual, it can cause an alteration in CD4+ T-helper cells phenotype, from a Th1 profile to Th2 profile. The Th1 is responsible for cell immunity while the Th2 is functioning in the production of antibodies. Glucocorticoid Hormones and HPA Axis The hypothalamus monitors and receives environmental information, and it's charged with the responsibility of coordinating responses through hormones and nerves (Dhabhar, 2014). The brains emotional portion is among the body parts that supply info to the hypothalamus. The brain commands the secretion of hormones process from either the pituitary glands or other tissues. Hence, corticotrophin releasing hormone is secreted by this i...
