Confocal image of the developing eye of a chick embryo. The dark region in the centre is the where the surface layer has invaginated to form the lens vesicle. The tissue surrounding this space is stai...

This photomicrograph shows the retina from the eye of a three-day-old zebrafish. The retina is viewed here from the front, as if the viewer is looking directly into the eye of the fish. This image is...

Figures 323 & 324 from Chapter 13 (Cilia and Flagella) of 'The Cell' by Don W. Fawcett M.D. The outer segments of the rods and cones of the vertebrate retina and many photoreceptors of invertebrates b...

Surface rendered models of chromatin organization from tomogram derived from a TEM image of epon section of a freeze-substituted mouse retina. (C) shows the region boxed in CIL:39743 where 4 regions o...

TEM image of epon section of a freeze-substituted mouse retina illustrating the unusual distribution of heterochromatin in rod receptor nuclei where the compact heterochromatin is centrally located. W...

TEM image of epon section of a freeze-substituted mouse retina illustrating the unusual distribution of heterochromatin in rod receptor nuclei where the compact heterochromatin is centrally located. C...

Freeze fracture images of synaptic junctions in the retina of Macaca mulatta. The electron micrograph in the top panel shows two invaginating synapses between cone and horizontal cells in the outer p...
