Question

Most sensitive part of Retina is called:

1. A. Black spot
2. B. Cornea
3. C. Yellow spot (Correct answer)
4. D. Blue spot

Correct Answer

Option C — Yellow spot

Detailed Solution & Explanation

The correct answer is Yellow spot.

Key Points

• The yellow spot, or macula lutea, is the most sensitive part of the retina, giving the sharpest and most detailed vision.
• At its centre lies the fovea centralis, packed densely with cone cells.
• The cornea is the transparent front covering of the eye and is not part of the retina at all.

Additional Information

• The blind spot is where the optic nerve leaves the eye; it has no photoreceptors, so nothing is seen there.
• The retina holds two receptor types: cones for colour and bright light, concentrated at the macula, and rods for dim light, spread across the periphery.
• Vitamin A deficiency impairs the rods first, causing night blindness.
