What is a Case Study?

“A case study is a narrative used to help you practice real-life analysis and communication skills. It is a learning tool that provides readers with “enough detail…to understand the nature and scope of the problem, and…serve as a springboard for discussion and learning” (O’Rourke, 2007, p. 391).

Use your textbook and academic resources from the Kaplan Library to support your responses.

Access the Kaplan Library directly from Course Resources for this class, or through the student portal. Be sure to cite and reference all your sources. The Kaplan Library has a feature that allows you to automatically create an APA formatted reference.

Your completed case study should be between 750–1000 words, and all sources must be properly cited using APA format.

1. Amy is cooking dinner for her family. She moves to pull a pot off the stove and accidently touches the burner. She reflexively pulls her finger away from the stove and immediately feels the pain.
   1. Which receptor neuron is responsible for sending information from her finger to her peripheral nervous system?
   2. Is this receptor neuron, an afferent or efferent neuron?
   3. Explain where the information from the receptor neuron is sent and how does it result in Amy moving her finger away from the stove.
   4. How many neurons are typically involved in this response? What are the names of these neurons?
   5. Evolutionarily, why do you think the human body has this system in place?
   6. What might happen if we did not have this response?
2. Glen, who is 45 years old, begins to notice that his hands shake (tremors) when he is performing everyday tasks such as signing his signature. His family members have noticed that he also has muffled speech and tends to shuffle when he walks. He is diagnosed with Early Onset Parkinson’s disease.
   1. What is Early Onset Parkinson’s disease?
   2. What specific cell type is affected in Parkinson’s disease?
   3. What is dopamine? What effects does dopamine have on the body?
   4. Explain the structure of a synapse and why Glen’s neurologist would prescribe him a dopamine agonist?
   5. Glen has genetic testing performed and it is determined that he does carry an autosomal dominant mutation in the SNCA gene associated with Early Onset Parkinson’s disease. Glen has three children. Would you advise his children to have genetic testing performed to determine if they also carry the disease mutation? Why or why not?
3. Patricia, who is 37 years old, discusses with her physician recent symptoms that she has experienced including blurred vision, numbness in her fingers and face, dizziness, fatigue and weakness. The physician performs multiple neurological tests and she is diagnosed with multiple sclerosis (MS).
   1. What is MS?
   2. Is MS a disease of the central or peripheral nervous system?
   3. What is the main cell structure affected in MS?
   4. How is the action potential of a neuron affected in MS?
   5. The origins of MS are not clear. What do scientists hypothesize to be the causes of MS?

Your assignment should be written in an essay format. The assignment requires you to include details from research including the course materials and sources you locate on your own. Remember to use APA format to cite your sources of information, both within parenthetical citations and also within a reference page at the end of the project.

Basic Writing Requirements:

• Between 750–1000 words not counting the title or reference pages.
• Include a title page, double space, font size 10 or 12.
• Include a well-developed introduction and conclusion
• Provide exceptional content.
• Demonstrate superior organization: use logic.
• Free of grammar and spelling errors.
• No evidence of plagiarism.
• Use the APA style for all citations.

• Simplify each expression using the rules of exponents and examine the steps you are taking.

• Incorporate the following five math vocabulary words into your discussion. Use bold font to emphasize the words in your writing. Do not write definitions for the words; use them appropriately in sentences describing the thought behind your math work.
• Principal root
  • Product rule
  • Quotient rule
  • Reciprocal
  • nth root

Refer to Inserting Math Symbols for guidance with formatting. Be aware with regards to the square root symbol, you will notice that it only shows the front part of a radical and not the top bar. Thus, it is impossible to tell how much of an expression is included in the radical itself unless you use parenthesis. For example, if we have √12 + 9 it is not enough for us to know if the 9 is under the radical with the 12 or not. Therefore, we must specify whether we mean it to say √(12) + 9 or √(12 + 9), as there is a big difference between the two. This distinction is important in your notation.

Another solution is to type the letters “sqrt” in place of the radical and use parenthesis to indicate how much is included in the radical as described in the second method above. The example above would appear as either “sqrt(12) + 9” or “sqrt(12 + 9)” depending on what we needed it to say.

Evaluate each expression. See Example 5. See the Strategy for Evaluating a^−m/n box on page 571.
