In adhesion junctions, cells are connected by membrane - associated proteins. These proteins link the cytoskeletons of adjacent cells or to the extracellular matrix. Membrane channels are mainly for ion or molecule transport, and extracellular filaments are not the main connecting elements in adhesion junctions.
