Question

How does a gap junction facilitate intercellular communication?

✓

Answer

Gap junctions are fine hydrophilic channels between two adjacent animal cells. These are formed with the help of two protein cylinders; called connexions. Gap junctions allow small signaling molecules to pass from one cell to another and thus they facilitate intercellular communication. Movement through gap junctions is controlled by pH and $Ca ^{2+}$ concentration.
