Eye – Microscopic Anatomy
The model illustrates the microscopic structure of the retina with choroid and sclera. The left side shows
the light microscopic appearance of the retina including the choroid and parts of the sclera and the com-
plex synaptic wiring diagram of the retina. The right part of the model shows a sectional enlargement with
the microscopic structure of the photoreceptors.
The retina consists of the following 10 layers:
1) Stratum pigmentosum (pigmented layer of retina)
2) Stratum nervosum (layer of rods and cones)
3) Stratum limitans externum (outer glial limiting membrane)
4) Stratum nucleare externum (outer nuclear layer)
5) Stratum plexiforme externum (outer plexiform layer)
6) Stratum nucleare internum (inner nuclear layer)
7) Stratum plexiforme internum (inner plexiform layer)
8) Stratum ganglionicum (ganglionic cell layer)
9) Stratum neurofibrarum (layer of nerve fibers)
10) Stratum limitans internum (inner glial limiting membrane)
