Connective tissues primarily feature three types of cell junctions: tight junctions, gap junctions, and desmosomes. Tight junctions create a barrier to prevent leakage between cells, while gap junctions facilitate communication by allowing small molecules and ions to pass between adjacent cells. Desmosomes provide mechanical strength by anchoring cells together, which is crucial for tissues subjected to stress. Each type plays a vital role in maintaining the integrity and function of connective tissues.
