Question

The order of the three layers of the cells in the retina of the 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

Hint: It is positioned next to the optic nerve. The aim of the retina is to receive light focused by the lens, translate the light into neural signals, and transmit these signals for visual recognition to the brain.

Complete answer: Rods, at low light, are responsible for vision. At higher light levels, cones are involved. The retina is a slight tissue layer that coats the inside of the flipside of the eye. It is positioned next to the optic nerve. The aim of the retina is to receive light focused by the lens, translate the light into neural signals, and transmit these signals for visual recognition to the brain.
As light reaches the eye visual information starts and transmits it to the brain through its axons, long fibres that make up the optic nerve, is processed by retinal ganglion cells. In the human eye, there are over a million retinal ganglion cells. Bipolar cells are retina interneurons that transfer visual data from amacrine to photoreceptors. A photoreceptor cell, which is capable of visual phototransduction, is a specialised type of neuroepithelial cell located in the retina.
So, the correct answer is “Option C”.

Note:
Through a layer of photoreceptor cells, the retina detects light. These are basically cells that are light-sensitive, responsible for sensing characteristics such as colour and strength of light. The retina processes the information that the photoreceptor cells obtain and transfers this information through the optic nerve to the brain. Basically, an image is viewed from the focal light by the retina, and the brain is left to determine what the picture is.
