in·ter·cel·lu·lar junc·tions

specializations of the cellular margins that contribute to the adhesion or allow for communication between cells; they include the macula adherens (desmosome), zonula adherens, zonula occludens, and nexus (gap junction).

intercellular junctions

The microscopic space between cells. These spaces are important in assisting the transfer of small molecules across capillary walls. These junctions may be widened by chemical or physical factors and are acted on by chemical mediators of inflammation to increase vascular permeability.
