1. Jefferson, a football back, suffered torn menisci in his right knee joint when tackled from the side. The same injury crushed his common peroneal nerve against the fibula head. What locomotor problems did Jefferson have after this?
2. As Harry fell off a ladder, he grabbed a tree branch with his right hand, but unfortunately lost his grip and fell heavily to the ground. Days later, Harry complained that his upper limb was numb. What was damaged in his fall?
3. Mr. Frank, a former stroke victim who had made a remarkable recovery, suddenly began to have problems reading. He complained of seeing double and also had problems navigating steps. He was unable to move his left eye downward and laterally. What cranial nerve was the site of lesion (be specific!)?
4. One of a group of rabbit hunters was accidently sprayed with buckshot in both of his gluteal prominences. When his companions saw that he would survive, they laughed and joked about where he had been shot. They were horrified and ashamed a week later when it was announced that their friend would be permanently paralyzed and without sensation in both legs from the knee down, as well as on the back of his thighs. What happened?
5. Charles Smythe, age 66, arrived at the clinic complaining of pain behind the left ear for the last few days. This morning, he woke up with difficulty moving the entire left side of his face. He has a masklike appearance to his face as he talks about his pain. He has a history of Type II diabetes mellitus, which is controlled by diet, and he has no known complications from this disease. His medical history is otherwise unremarkable. He is 6 feet tall with a weight of 190 pounds. He exercises regularly by walking several miles a day. Until this recent facial paralysis, Mr. Smythe felt well and had no complaints.
On a physical examination, it is noted that Charles feels a drawing sensation on the left side. He is unable to close the eye, wrinkle his forehead, smile, whistle or grimace. His face sags on the left side. His blood pressure and pulse are 146/88 and 92, respectively. His hand grips are strong and equal bilaterally. He has no weakness in either of his legs. Based on the history and physical examination, what would you diagnose his condition as? Why?
