Question 1
The function of the auditory ossicles is to:
transmit the light reflex to the light cone.
transform sound vibrations into mechanical waves for the inner ear.
to capture sound waves from the external ear for transmission into the middle ear.
to separate the inner ear from the middle ear.
Explanation:
The function of the auditory ossicles is to transform sound vibrations into mechanical waves
for the inner ear

Vertigo symptoms associated with neurologic conditions include: ataxia, diplopia, and
dysarthria. Symptoms associated with cardiovascular conditions and vertigo include

Question 3
A 60-year-old was concerned about a yellowish colored lesion above her right eyelid.
Findings revealed a slightly raised yellowish, well circumscribed plaque along the
nasal area of her right eyelid. This finding is most consistent with:
a pinguecula.
a chalazion.
episcleritis.
xanthelasma.
Explanation:
Slightly raised, yellowish, well-circumscribed plaques appearing along the nasal area of one
or both eyelids are consistent with lipid disorders and called xanthelasma. Pinguecula refer to
harmless, yellowish, triangular nodules in the bulbar conjunctiva on either side of the iris. A
chalazion is a nontender nodule usually on the underside of the eyelid. Episcleritis is an ocular
inflammation of the episcleral vessels.
