Parts A, B, C and D of the human eye are shown in the diagram. Select the option which gives correct identification along with its functions/characteristics:
-
- B-Blind spot-has only a few rods and cones
- C-Aqueous chamber-reflects the light which does not pass through the lens.
- D-Choroid-is anterior part forms ciliary body
- A-Retina-contains photoreceptors-rods and cones.
Correct Option: D
Retina is the innermost layer of eyeball and it contains three layers of cells - ganglion cells, bipolar cells and photoreceptor cells. Photoreceptor cells are not present in blind spot. The space between the cornea and the lens is called the aqueous chamber and contains a thin watery fluid called aqueous humor. Choroid is anterior part of external sclera layer of eyeball while ciliary body is anterior part of middle choroid layer.
