Question

Quizplus · Accepted Answer

The oculomotor, trochlear, and abducens nerves are responsible for the movement of the eyes, and testing their function involves evaluating the patient's extraocular movements. This can be done by asking the patient to follow a moving object with their eyes or testing their ability to follow a sequence of specific eye movements. Shining a light into the pupils (A) tests the function of the optic nerve, while a visual acuity test (B) tests the function of the optic nerve and the occipital lobe of the brain. Closing one nostril and presenting a strong smell (D) tests the function of the olfactory nerve.
