Colorized scanning electron micrograph of a mouse trachea and its red blood cells.

These examples of ependymal epithelium from the rat brain represent epithelia that lack zonulae occludentes. Further, there appears to be no consistent order to the junctional specializations that are...

Gap junctions in ciliary epithelium under conditions of oxygenation (upper) and anoxia (lower), in tissue prepared by ultrarapid freezing using liquid helium. Under oxygenated conditions, the connexo...

Figure 371 from Chapter 15 (Cytoplasmic Inclusions) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Ferritin crystal in midgut cell of the widefooted treehopper Campylenchia latipes. Crystallization o...

Figures 446 (upper) and 447 (lower) from Chapter 16 (Cytoplasmic matrix and cytoskeleton) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Microvilli of the brush border of cat intestinal epithelium sho...

Electron micrograph showing the brush border of intestinal epithelial cells of the rat. The parallel microvilli of the brush border are about 0.1 µm wide and 1.0 µm in length. Image by Jean Paul R...

Histology sample illustrating the pseudostratified, ciliated columnar epithelium of the trachea. Note that the basement membrane underlying this particular epithelium is especially prominent. This im...

Representative examples of gap junctions from vertebrates (ciliary epithelium from the eye of a Macaca mulatta, upper) and invertebrates (inverted gap junctions from cells of the mid-gut of the horses...

Images of desmosomes from conventional EM and freeze fracture preparations show transmembrane filaments that link two hemidesmosomes. Upper: section of a cell boundary in the ciliary epithelium of th...

Figure 317 from Chapter 13 (Cilia and Flagella) of 'The Cell' by Don W. Fawcett M.D. The inconsistent orientation of the cilia in scanning micrographs does not accurately reflect their state in the li...
