Junctional complex
This junctional complex is located between adjacent cells of a ciliated epithelium. The apposition of the plasma membranes of the zonula occludens prevents leakage of luminal contents into the intercellular space. Desmosome- and zonula adherens-associated filaments account for the cytoplasmic electron density adjacent to these structures. 50,000x

- Desmosomes >
A desmosome (macula adherens) is the third component of the junctional complex. Desmosomes are not only associated with junctional complexes, but occur around the perimeter and at all levels of the cell. Therefore, in this section, two desmosomes are included in close proximity to the zonula adherens.
