Junctional complex
Junctional complexes are found at the apex of epithelial cells and have three components: Zonula occludens, a band or belt encircling each cell that seals the lumen from the intercellular space; Zonula adherens, also a band that attaches adjacent cells to each other; and Desmosomes (maculae adherentes), which also provide cell attachment but consists of disk-like structures rather than encircling belts. Desmosomes are also distributed in other regions of the cell.
