Eye's retinal cells and layers. Artwork of the cells that make up the layers of the retina. The area shown here is highlighted at upper left on a diagram of the whole eyeball. Light arriving from lower right passes through a layer of nerve tissue (orange and blue) to reach the light-sensitive photoreceptor cells. These are of two types, rods (green) and cones (purple). The electrical signal from these cells is passed to bipolar neurons (orange) and then to ganglion nerve cells (blue). The nerve impulse then travels along nerves (yellow) to the optic nerve.
