Question

The order of the three layers of cells in the retina of human eye from inside to outside is

• A. Bipolar cells, photoreceptor cells, ganglion cells
• B. Ganglion cells, rods, cones
• C. Ganglion cells, bipolar cells, photoreceptor cells
• D. Photoreceptor cells, ganglion cells, bipolar cells
• E. Ganglion, photoreceptor cells, bipolar cells

Answer 1

Answer: (C)

The retina has three layers of nerve cells. The ganglion cells lie innermost in the retina, while the photoreceptive cells lie outermost. Between the ganglion cell layer and the layer of rods and cones there are layers of bipolar, where synaptic contacts are made. In the outer rods and cones connect to the vertically running bipolar cells, and the horizontally oriented horizontal cells, connect to ganglion cells.

So, the correct answer is 'Ganglion cells, bipolar cells, photoreceptor cells'
