visual cells

visual cells
the neuroepithelial photoreceptor portion of the retina, the first neurons of the vertical linkage of the retina, consisting of two kinds of cells: the retinal cones and retinal rods (see under cone and rod). Each rod or cone has an inner, axonal, process synapsing with one or more horizontal or bipolar retinal cells, has a soma in the outer nuclear layer, and has a photosensitive outer dendritic process that extends toward the pigment epithelium. See also ganglion c. Called also photoreceptor c's.
