This junction consisted of a central region with a large amount of electron dense material associated with the I band of the myofibrils, and a zona occludens that extended from the region of the myofilament to the periphery of the cell. Intercalated disks have been more frequently reported in cardiac muscle. The structures appear to be sites where cell membranes between muscle cells interdigitate extensively. This ensures satisfactory adhesion to prevent separation during contraction and allows exchange of ions through gap junctions for communication between cells. |
