Sample QuestionEmma is a 64-year-old woman who has had heart disease for many years. While carrying chemicals down the stairs of the dry-cleaning shop where she worked, she suddenly lost control of her right leg and arm. She fell down the stairs and was able to stand up with some assistance from a coworker. When attempting to walk on her own, she had a very unsteady gait, with a tendency to fall to the right side. Her supervisor asked her if she was all right, and noticed that her speech was very slurred when she tried to answer. He called an ambulance to take her to the nearest hospital. The physician who was called to see Emma in the emergency room noted that her speech was slurred as if she were intoxicated, but the grammar and meaning were intact. Her face appeared symmetric, but when asked to protrude her tongue, it deviated toward the left. She was unable to tell if her right toe was moved up or down by the physician when she closed her eyes, and she couldn't feel the buzz of a tuning fork on her right arm and leg. In addition, her right arm and leg were markedly weak. The physician could find no other abnormalities on the remainder of Emma's general medical examination. Where in the nervous system could a lesion occur that causes arm and leg weakness, but spares the face?
