WebJul 22, 2024 · The tight junction definition is a type of cell junction that promotes a tight seal between two cells. Tight junctions are also called zonula occludens or occluding junctions. Tight Junctions ... WebTight junctions are different from gap junctions because they are the connections that form when cells are squished up against one another. In this case, the cell membranes are connected, but the contents of each cell are not connected in any way. There are no tubes here, but there is an impermeable layer in between the cells.
