Question

The membrane that covers the outer surface of the eye and lines the eyelids is the ________.
A) choroid
B) sclera
C) conjunctiva
D) retina

Accepted Answer

The conjunctiva is the thin, transparent mucous membrane that covers the outer surface of the eye and lines the inside of the eyelids. The choroid is a layer of tissue between the retina and sclera that contains blood vessels and helps nourish the retina. The sclera is the tough, white outer layer of the eye. The retina is the layer of tissue at the back of the eye that contains photoreceptor cells and processes visual input.
