Which of the Following is a True Statement

Question

Which of the following is a true statement?
A)Cones are more numerous than rods.
B)Cones are most densely concentrated in the fovea centralis.
C)Rods are most densely concentrated in the macula lutea.
D)Cones increase in density toward the periphery of the retina.

Accepted Answer

Cones are less numerous than rods in the retina, but they are most densely concentrated in the fovea centralis, which is the region of the retina responsible for acute central vision. Rods, on the other hand, are most densely concentrated in the peripheral retina, and are especially important for vision in low-light conditions. The macula lutea is a yellowish spot near the center of the retina, containing both rods and cones, but not in the highest density.
