How does a gap junction facilitate intercellular communication?
Answer- Gap junction facilitate intercellular communication. These junctions are present in the form of fine hydrophilic channels between adjacent cells. The gap junctions are produced due to the help of protein cylinders called Connexus. The junctions allow signal molecules to pass from one cell to another. Thus, ensuring intercellular communication. This movement of cells is controlled by the Ca2+ concentration and the pH levels.
