Question

Quizplus · Accepted Answer

The cornea and the sclera make up the outer layer of the eye. The cornea is very sensitive to touch. The middle layer, the choroid, has dark pigmentation to prevent light from reflecting internally. The trigeminal nerve (CN V) and the facial nerve (CN VII), not the trochlear nerve (IV), are stimulated when the outer surface of the eye is stimulated. The retina, in the inner layer of the eye, is where light waves are changed into nerve impulses. The outer layer of the eye is not darkly pigmented, the sclera is white and the cornea is transparent. It is the middle layer, the choroid, that has dark pigmentation to prevent light from reflecting internally. The true statement about the outlayer of the eye is that it is made up of the cornea and the sclera.
