Description

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 present between these cells. Images courtesy of Enrico Mugnaini, are Figure 73 (upper), 74 (middle), 75 (lower) from Chapter 3 (Junctional Specializations) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. A PDF copy of the accompanying chapter is available on the ASCB's BioEDUCATE website. A PDF copy of the accompanying chapter is available on the ASCB's BioEDUCATE website.
