문제 L2.4

Following a stroke, a patient lost vision in the left visual field. Name several structures in the brain that could have been damaged by the stroke to have caused this vision loss. Be specific as to right or left side.

문제 L2.2

In which direction would you be unable to move your right eye if your right abducens nerve were damaged?

문제 L2.1

Explain what would happen to your sense of smell if there were no basal cells present in the olfactory epithelium.

문제 L2.5

Why do you have the sensation that you are still spinning immediately after stopping?

문제 L2.3

If a patient suffers visual impairment only in one eye, why must the damage be located in the visual pathway prior to the optic chiasma?

문제 3

In an olfactory neuron, the binding of a(n) ______ to its membrane receptor triggers a(n) _______ potential in the axons of the ______ nerve.

문제 L3.5

Mrs. Flores is a 45-year-old female who suffered a fracture of the ethmoid bone as the result of a car accident. Several days later, she complained that she couldn't taste her food very well. How is her injury related to the loss of taste sensation?

문제 L3.6

Your 60-year-old patient, Mr. Guster, has Bell's palsy, which causes dysfunction of those portions of the facial nerve that control muscles of facial expression. He is surprised when you tell him to tape the eyelids of his right eye closed at night to prevent dryness. Why might Bell's palsy cause dryness of the eye on the affected side?

문제 L3.3

If severe congestion from a cold prevented your pharyngotympanic tube from opening, what could happen to your tympanic membrane? Explain your answer.

문제 L3.4

Suppose the round window in your middle ear became very stiff. What effect would this have on hearing, and why?

문제 L3.1

Mr. Spencer suffers loss of taste sensation. Tests reveal that his taste buds and salivary glands are functional. What other structures might be impaired that would explain his loss of taste?

문제 L3.2

Your friend tells you that she has just been diagnosed with myopia, and she wonders if staring at her computer screen too much might have caused her problem. What do you tell her?
