C
Gap junction
D
Adherens junction
Verified step by step guidance1
Understand the function of each type of membrane junction: Tight junctions, Desmosomes, Gap junctions, and Adherens junctions.
Tight junctions are specialized connections between adjacent cells that create a seal to prevent the passage of materials between the cells.
Desmosomes provide mechanical strength by anchoring cells together, but do not prevent material movement between cells.
Gap junctions allow direct communication between cells by permitting the passage of ions and small molecules.
Adherens junctions connect cells through actin filaments, providing structural support but not preventing material movement between cells.
