Assessment Task 1

1. Assessment Task 1 Advanced Medical Science

2. Marking Guidelines Adherence to all requirements (20 marks): Clearly addressed the question with accurate information (4 marks) Information clear and concise (3 marks) Clearly linked the anatomical design and physiology to explain the question (4 marks) Correct spelling and terminology (2 marks) Successfully summarised key ideas, issues and or findings (5 marks) Stayed within the word length (2 marks) This section will be equally allocated to both aspects of the assessment task.

3. Marking Guidelines 2. Topic: a) Describe the anatomical and physiological norms of the chosen topic (10 marks). (5 points, with an example of each point) b) Identify the stressors in which induce the chosen immune response (5 marks). (Opening sentence and list 5 stressors) c) Expand to explain how these stressors change homeostasis and ultimately immune function (15 marks). (3 specific points on general homeostasis with 1 example on each point; 2 specific points on immune function and homeostasis with 2 examples for each point). d) State the diagnostic and monitoring tests/methods you would use to determine the chosen immune response level of functioning (5 marks). (List 5 tests-it does not ask you why you chose these tests). e) At the cell level, indicate how the cell responds/adapts to accommodate the presenting stressors (Early physiological changes) (8 marks). (flow chart, diagram: outlining how a cell adapts to a stressor). (4 points on how the cell responds (initial response) (4 points on how it adapts). f) Describe the impact on other organ systems and how the body might respond (10 marks) (Select 5 systems and describe 1 point on the relationship between the system and the current stressor) g) Identify the chronic responses/adaptation to cells, and how the systems plan to accommodate the continuing stressors on the body if left untreated (7 marks). (select a condition associated with your stressor, identify 7 ways in which the body can be affected.

4. Marking Guidelines Examples: Explain the anatomical and physiological processing of afferent information: General senses – thermoreception (changes to temperature), chemoreception (changes in pH): Special senses: Gustation (taste buds, primary taste sensations). Anatomy- Tactile receptors and anatomy (touch, pressure, vibration). Expand to Explain how the stressor, in general changes homeostasis and ultimately GI function: How does stress can homeostasis? e.g. mental clarity; Fight: Flight response (Selye’s general adaptation syndrome); GI specific: elimination , digestion (peristalsis), appetite suppression. Hormones involved: stress boosts ghrelin.

5. Marking Guidelines Examples: c) At the cellular level indicate how the cell responds/adapts to accommodate the presenting stressors of the immune system: Increased cortisol (stress hormone) suppresses T lymphocytes. How does this affect a T cell mediated autoimmune condition. Oxidative stress. Alternatively c) Inflammation response, how it protects and degrades the body: A focus point may be the role inflammation plays in atherosclerosis. What are the cellular mechanisms involved ? e.g. repair, onset of inflammation, plaque , inflammatory cytokines.

6. Marking Guidelines d) Identify the chronic responses/adaptation to cells, and how the system as a whole accommodates the continuing stressor if the body is left untreated.: Identify changes made by a cell in response to an adverse environmental change- epigenetics -point out the phenotypic (behavioural/appearance) or genetic (Okinawa) changes that can come about in the next generation.

7. Marking Guidelines Summary (20 marks) (maximum of 300 words for each summary) Briefly outline (2 sentences) the anatomical and physiological norms , provide 1 example (3 marks). Identify the specific stressors noted (List) (2 marks). Briefly outline (Graph/Flow chart) homeostatic changes (5 marks). Briefly outline the adaptation discussed and provide 2 examples (5 marks). Briefly outline the impact on other organ systems and provide 2 examples (5 marks).
