These junctions are most abundant in tissues that are subject to constant mechanical stress such as skin and heart . </P> <P> Desmosomes, also termed as maculae adherentes, can be visualized as rivets through the plasma membrane of adjacent cells . Intermediate filaments composed of keratin or desmin are attached to membrane - associated attachment proteins that form a dense plaque on the cytoplasmic face of the membrane . Cadherin molecules form the actual anchor by attaching to the cytoplasmic plaque, extending through the membrane and binding strongly to cadherins coming through the membrane of the adjacent cell . </P>
