<P> Tight junctions , also known as occluding junctions or zonulae occludentes ( singular , zonula occludens ) , are the closely associated areas of two cells whose membranes join together forming a barrier virtually impermeable to fluid . It is a type of junctional complex present only in vertebrates . The corresponding junctions that occur in invertebrates are septate junctions . </P>
