it surrounds the lateral surface of epithelium cell and is located just below the tight junctions. here opposing membrane of the cell makes a gap of 15nm-20nm where a middle electron molecule is present presumed to be glycoprotiens. on the cytoplasmic face of the adjacent cell where intermediate junction occur small amount of the small electro- densed substance are present. numerous filament are embedded in this electron densed plaque, which radiates away from the intermediate junctions into the cytoplasmic matrix and are often continuous with the filaments of terminal web. this structure helps in holding adjacent cells(bidur marasini sichuan university)
