Question

Area of the retina having the maximum number of cones is ________.

• A. Conjunctiva
• B. Iris
• C. Blind spot
• D. Fovea centralis

Answer 1

The correct option is D Fovea centralis

A. Conjunctiva is a thin transparent membrane lining the eyelids and protects the delicate cornea and front portion of the eye.

B. The amount of light entering the eye is regulated by iris which controls the size of pupil.

C. Blind spot is the region in eye where no photoreceptor cells are present.

D. Fovea centralis is the central pit of macula lutea which is a yellowish pigmented spot located laterally to the blind spot. Visual resolution is maximum at fovea as it has maximum number of cones (photoreceptor cells in retina which are associated with the daylight vision and colour vision).

So, the correct answer is 'Fovea centralis'.
