Illustration of nerve cells in mammalian retina

Illustration of the layers of nerve cells comprising the mammalian retina, the light- sensitive layer of the eye. At bottom, the outermost layer of pigmented cells supports a number of rod- & cone-type photosensitive cells. The rods outnumber cones by about 20:1 - hence only cones are shown here. The cell bodies above the rods & cones layer form the integrating bipolar cell layer; a single cell body may be seen to serve several rod receptors via numerous synapses (junctions). The upper ganglion layer of cell bodies belong to fibres comprising the optic nerve (top)
