The membrane surfaces of neighboring cells can simply bind to one another mechanically, thereby forming junctions of an odd shape that are called digitiform intercellular junctions. Thus, the cell surfaces form some finger-like projections and ridges (they are slightly thickened terminally) that enter the compliant pits of opposite cells. The image shows such junctions constituted by adjacent surfaces of three epithelial cells, which are enterocytes #1, #2, #3. A digitiform junction has a high mechanical strength. These digitiform intercellular junctions are not a specialized type of membrane connections since they are only provided by their shape. However, they are often accompanied by local specialized adhesive junctions of the membranes that are desmosomes #1, #2, #3, #4.
