Transmission electron micrograph showing the apical region of two adjacent epithelial cells. Numerous microvilli project from the cell surface into the lumen. At the cell junction, three distinct structures are labeled: a tight junction at the apical border, an adherens junction below it, and a desmosome further down. The cytoplasm contains various organelles and vesicles. The image illustrates the ultrastructural organization of cell junctions and surface specializations in epithelial tissue.
