Adult Retina
Vertebrates have ten identifiable layers formed from neurons, their processes (nerve fibers), membranes, photoreceptors and pigmented cells. Light must pass through nearly all these layers to the photoreceptors.
- Inner limiting membrane - Müller cell footplates.
- Nerve fiber layer - retinal ganglion axons eventually the optic nerve.
- Ganglion cell layer - neuronal cell bodies of retinal ganglion cells, their axons form the nerve fiber layer and eventually the optic nerve.
- Inner plexiform layer - another layer of neuronal processes.
- Inner nuclear layer - neuronal cell bodies
- Outer plexiform layer - another layer of neuronal processes.
- Outer nuclear layer - neuronal cell bodies
- External limiting membrane - layer separating inner segment portions of photoreceptors from their cell nuclei.
- Photoreceptor layer - rods and cones that convert light into signals.
- Retinal pigment epithelium.
