Question

Quizplus · Accepted Answer

The impermeable junctions that join the lateral edges of epithelial cells near their luminal borders and prevent movement of materials between the cells are called tight junctions. Gap junctions are channels that allow small molecules and ions to pass between adjacent cells. Desmosomes are anchoring junctions that connect adjacent cells and provide mechanical stability. Luminal junctions are not a recognized type of cellular junction.
