Aria is a 30-year-old woman who recently presented in the emergency room after a bicycle accident. The ER nurses treated several lacerations and abrasions to the right side of Ariaâ€™s face and her right arm. X-ray images showed a complete transverse fracture of Ariaâ€™s right wrist and fractures to her right temporal bone. The attending physician placed a cast on Ariaâ€™s arm and proceeded to examine her for the extent of the head trauma.
When asked to walk across the room, Aria complained of dizziness and had trouble keeping her balance. Aria was unable to hear clearly through her right ear and when a struck tuning fork was placed on her forehead, she could hear it only on the left side. When asked to sniff a vial of vanilla extract, Aria correctly identified the odor. An eye exam revealed that Ariaâ€™s visual acuity and peripheral vision were normal. The doctor then asked Aria to follow a penlight with her eyes as he moved the light to Ariaâ€™s right, left, up, down, and towards her nose. Both eyes tracked the light as normal. The doctor examined Ariaâ€™s face for symmetry and observed some weakness in the eyelids, eyebrows, lips, and forehead on the right side. A taste test revealed that Aria was unable to distinguish sweet and salty tastes on the anterior right side of her tongue. Aria was able to feel a warm probe applied to her forehead, cheek, and chin. When asked to clench her jaw, the physician observed a strong and symmetrical contraction. Ariaâ€™s gag reflex was normal.
Based on her symptoms, the physician concluded that Aria had cranial nerve damage. He advised his patient that she may require surgery and sent her back to radiography for thin-slice CT scans of her skull.
For this assignment, you are the physician! Your task is to determine which cranial nerve(s) are damaged in Ariaâ€™s case. You will use the data you gathered in lab as the â€œnormalâ€ or control subject. Use the description of Ariaâ€™s symptoms in the case given above to formulate data for an â€œabnormalâ€ or experimental subject. Compare the data from the control subject (your lab partner) to the data for the experimental subject (Aria) to determine what sensory or motor deficits Aria is experiencing. Use your knowledge of the anatomy and function of each cranial nerve to determine which cranial nerve or nerves were affected by her injuries. To write your lab report, follow the format specified on the last page of this document and use the rubric provided to guide the content.

Format:Your paper must follow the format outlined below. The format of this paper follows the APA research report format. An example of this format can be found at: http://www.thewritesource.com/apa/apa.pdf
Title Page:The title page should be on a separate sheet of paper and contain
the title of the report, your name, the name(s) of your lab partner(s),
the course number and the date that the report was submitted.
The body of the paper should contain the following clearly labeled sections:
Abstract:In this section, you will include a single paragraph to summarize the background and main results. Write this part last.
Introduction: An introduction provides a concise statement, in paragraph form, of the
purpose or aims of the experiment as well as the relevant background about the experiment. Although the introduction varies with the style of the author and tests performed, it should only contain information that is relevant to the case. The introduction should be about one typed page in length. You must include a hypothesis based on the information in Ariaâ€™s case. Give the reasoning for your hypothesis based on what is known about the function of the cranial nerves.Make sure to cite all references properly in the body of the paper
Procedures:This section explicitly describes the details of the tests performed. Do not copy directly from the lab manual but do cite the manual as a reference. Describe in your own words the procedures you used to test the functions of cranial nerves.
Results:This section is used to present your results. You should not report raw data. It should be tabulated and presented in the form of tables and graphs. Make sure that all tables and graphs are labeled appropriately. Be sure to include data for both the control and the experimental subjects.
Discussion:The data is analyzed and discussed in this section.It is important to interpret the data, not simply restate it.Here is where you relate your experimental results to existing knowledge of the function of the cranial nerves.Are your results in agreement with your hypothesis?Discuss this, and try to explain any discrepancies.What are the main points of uncertainty in interpreting your data?You may speculate, but acknowledge that you are doing that.Include suggestions that you may have for improving the design of the tests.If you use material from other sources to support your discussion, you must cite the reference.
Literature Cited:Use the APA format for citations within the paper and in your reference list.Consulthttp://owl.english.purdue.edu/owl/resource/560/01/
