Eye - Retina

The retina consists of the retinal pigment epithelium and neurosensory retina. The neurosensory retina includes multiple layers of neurons and some glia. The outer nuclear layer contains the cell bodies of rod and cone photoreceptors. The inner nuclear layer contains the cell bodies of multiple neurons. These include horizontal cells and amacrine cells (interneurons), bipolar cells, interplexiform cells and the radial glial cells of Mller. The ganglion cell layer contains the cell bodies of a variety of ganglion cells that send their axons out the optic nerve. Sandwiched between the three nuclear layers are plexiform layers (outer and inner) that contain many of the retinal synapses. Note the highly vascular choroid at top. UCLA Histology Collection.
