Questions 1 and 2:
Common painful conditions associated with the leg and foot are IT band syndrome and plantar fasciitis. For each one, describe the underlying structure that is involved, describe its normal function, and give one specific symptom of the condition (what action is painful). For example: “leg pain” is not specific but “knee pain while horseback riding” is.
1. IT
2. Plantar fasciitis
Question 3: In the lower leg, what is the functional reason why the muscle group on the dorsal leg (calf) is so much larger than the muscle group in the ventral region of the leg?
Question 4: You are debating whether to order fugu at a sushi bar. Fugu is raw puffer fish – very tasty but parts of it contain tetrodotoxin (TTX). TTX selectively blocks voltage-regulated sodium channels. A similar toxin is found in salamanders, but they are not on the menu. You remember a fugu episode of The Simpsons and know the toxin can kill you. Why could you die after eating TTX?
Question 5: Joe Raboski is 26 years old and a senior in college. A few months ago he started a new job laying carpet 30 hours a week. This involves a lot of kneeling, and lately kneeling has become so painful that he has had to take some time off. What is the most likely problem? Explain your choice.
Question 6:People with albinism have vision problems – what type and why?
Question 7: Two months before her wedding, 29 year old Tracy woke up to discover she had trouble moving the left side of her face. Over the next two days the facial muscles on the left side became even less responsive. In addition, the left eye was producing excessive tears and was difficult to close, she little sense of taste on the left side of her tongue, she was drooling out of the left side of her mouth because she had trouble controlling her lips, and sounds seemed louder through her left ear. Considerably alarmed, she went to the clinic to see what was wrong with her. During the examination, muscle function below the face was normal and she reported that she did not have a headache. The doctors based their diagnosis on that information, her various symptoms and the moderate degree of facial paralysis she showed. They predicted that the symptoms should go away on their own, and she might be almost back to normal in time for her wedding. She could take some anti-inflammatory medicines to help in her recovery, but time was the biggest factor in her recovery. What diagnosis did they give her and what was the physical reason for the facial paralysis and other problems?
Question 8: Michael is the resident advisor (RA) for a college dorm – the students on his floor are mostly freshmen, with a few sophomores. When he returned from his evening statistics class last week he was told one of his residents was running a high fever. He quickly went to check on the student, who was curled up in his bed with the lights out because they hurt his eyes. The student said he had had a bad headache most of the day and it got worse when he turned his head – in addition his neck hurt and felt stiff when he tried to turn it. He felt too tired to get out of bed, and wasn’t sure whether he had eaten or gone to classes that day. Michael got his resident to the ER immediately and told the doctors that the student had seemed fine the day before. The student was admitted to the hospital and a spinal/lumbar tap performed. Culture of the fluid showed it was aseptic. The student was sent home after a couple of days with the expectation of a full recovery in a couple of weeks. What disease is the most likely diagnosis?
Question 9: A stroke is a serious, potentially life-threatening emergency, and you need to act FAST. What does the acronym FAST stand for? Describe one common symptom of stroke not included in FAST.
