Question
Just 2b and 2c HLTH 301 2018: Lab 4 Name: Exercise 2: Case Study Annie, the tired swimmer, by Allison Russo, Morgan Falk, and Phil Stephens Annie felt despondent. Her teammates were being kind to her, but she knew that she was the reason that her team lost the swim meet against the neighboring college. To add insult to injury, she had to squint hard to see her sub-par times on the scoreboard. Even swim practice, which helped relieve her stress in the past, had become taxing and she often found it difficult to breathe. Her coach noticed that her times were getting worse, even though he could see that she was working hard in practice. Annie told the doctor about her symptoms, who recommended she see a neurologist. 2a. What were Annie's symptoms? fatigue and blurred vision At the neurologist office, Annie had been subjected to several different tests and finally got to see the doctor. The neurologist skimmed through the chart, "Hmm, blurred vision, weak fingers, and decline in swimming performance. OK, let's see what we found out today. First, the nerve conduction and the electromyography (EMG) tests; these are the only results we have right now. This was the test when they put sticky electrodes on your skin, remember? One set of electrodes stimulated the nerve and another recorded its response a little way down the nerve. There is no nerve fatigue and the conduction velocity is fine. Now, the electromyography test involves recording from a muscle; it was done in two stages. The first stimulated the muscle directly, and there isn't too much out of the ordinary there. The seconcd is when the nerves were stimulated and the muscle response was recorded. These results concern me because the muscle response decreased quickly during repeated nerve stimulation, indicating that your muscle response fatigued over time." 2b. According to the conduction test, was Annie's nerve function normal? 2c. According to Annie's EMG test, was Annie's skeletal muscle function normal? What aspect of it?Explanation / Answer
2b) yes Annie's nerve function was normal according to conduction test as there was no nerve fatigue and conduction velocity was fine according to the neurologist.
2c)no, Annie's skeletal muscle system was not normal.when the nerves were stimulated, muscle response decreased quickly during repeated nerve stimulation indicating that muscle response fatigued over time.
