Question

which of the following statements regarding the retina is not true?
a light strikes the retina at the macula lutea.
b the center of the macula lutea is the fovea centralis.
c the point of sharpest vision is the optic disk.
d rods and cones are found in the retina.

Explanation:

• Option A: Light does strike the retina at the macula lutea.
• Option B: The center of the macula lutea is indeed the fovea centralis.
• Option C: The optic disk is the blind spot (no photoreceptors), not the point of sharpest vision. The point of sharpest vision is the fovea centralis.
• Option D: Rods (for dim - light vision) and cones (for color and bright - light vision) are found in the retina.

Answer:

C. The point of sharpest vision is the optic disk.
