Question 1

Conduction deafness may result from earwax buildup or the fusion of the ossicles.

Accepted Answer

A) True 
 B)False  True

Question 2

Describe the pathway of light through the eyeball and the process of light refraction.

Accepted Answer

Light travels through the cornea, aqueous humor, lens, and vitreous humor before being focused on the retina during normal vision. Refraction by the cornea and humors is constant, whereas the lens changes its shape to be either more or less convex as needed. The greater the convexity, the more light is bent.

From the optic nerve, the visual pathway continues to the optic chiasma, optic tracts, thalamus, optic radiation, and then visual interpretation occurs in the occipital lobe.

Accepted Answer

A) True 
 B)False  True

Accepted Answer

A)  optic disc 
B)  blind spot 
C)  ciliary body 
D)  vitreous humor 
E)  fovea centralis
