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...

Electron micrograph of the junctional complex of intestinal epithelial cells of the rat shows the apical-most zonula occludens (tight junction), the zonula adherens (medium junction) and the macula ad...

Upper: capillary endothelial cell junction in the rete mirabile of the gas bladder of the toadfish Opsanus tau shows dense intracelluular plaques and the central dense line in the intercellular space,...

Upper panel, adjoining portions of two cells in the stratum spinosum of hamster cheek pouch epithelium shows desmosome junctions between two cells. Lower, a portion of the basal surface of a cell in ...

Transmission electron micrograph of intercalated disks with a desmosome from the atria of mouse cardiac muscle cells. The intercalated disks are where the junction of two opposing membranes of adjace...

Upper: a gap junction on the boundary between two hepatic cells shows a typical narrow and straight interface. Lower: in some preparations, gap junctions appear curved, and project into one of the ce...

This is a view of apical domains of two adjacent hepatocytes showing the junctional complexes that attach cells to one another. The canaliculus is defined by the cell membranes of two adjacent liver c...

This is a view of apical domains of two adjacent hepatocytes in the guinea pig liver, showing the junctional complexes that attach cells to one another. The bile canaliculus (BC) is defined by the cel...

Epithelia of invertebrates contain zona continua and septate junctions not found in mammals. Left, zonula continua from gut epithelium of a flea; right, septate junction from the midgut epithelium of...

A freeze fracture replica of a Sertoli cell junction from rat testis shows more than 50 rows of particles along the E-face. Image from Gilula, Fawcett and Aoki, Dev. Biol. 50: 142-168 (1976), reprint...
