tight junction

tight junction
an intercellular junction between epithelial cells, at which the adjacent plasma membranes are joined tightly together, separated by only 1 to 2 nm and forming a beltlike seal; these junctions occlude the intercellular space and limit intercellular passage of small ions and molecules. Called also occluding j. and zonula occludens.
