AP PSYCHOLOGY

Detailed explanation-1: -Macula lutea is the part of the retina that is responsible for sharp, detailed central vision (also called visual acuity). The macula lutea, also called fovea, contains a very high concentration of cones.

Detailed explanation-2: -Fovea: the central focal point in the retina, around which the eye’s cones cluster. Optic nerve: the nerve that carries neural impulses from the eye to the brain.

Detailed explanation-3: -The fovea centralis is a small, central pit composed of closely packed cones in the eye. It is located in the center of the macula lutea of the retina.

Detailed explanation-4: -the cones are concentrated in the fovea, whereas the rods predominate in the peripheral retina.

Detailed explanation-5: -In the fovea, cone density increases almost 200-fold, reaching, at its center, the highest receptor packing density anywhere in the retina. This high density is achieved by decreasing the diameter of the cone outer segments such that foveal cones resemble rods in their appearance.
