The photoreceptors are most tightly packed into a specific part of the retina called the ________.
A) optic nerve
B) fovea
C) ciliary body
D) choroid

Question

Quizplus · Accepted Answer

The fovea is a small indentation in the retina where the photoreceptors are most densely packed. This region provides the sharpest and clearest vision, as it contains a high concentration of cone cells which are responsible for color vision and visual acuity. The optic nerve is a bundle of nerve fibers that transmits visual information from the eye to the brain. The ciliary body is a structure that helps to control the shape of the lens, and the choroid is a layer of tissue that provides nutrients and oxygen to the retina. Neither of these structures is specifically associated with the high density of photoreceptors found in the fovea.
