Intercalated discs support synchronised contraction of cardiac tissue. They occur at the Z line of the sarcomere and can be visualized easily when observing a longitudinal section of the tissue. Three types of cell junction make up an intercalated disc â fascia adherens, desmosomes and gap junctions.1  Fascia adherens are anchoring sites for actin, and connect to the closest sarcomere. 2  Desmosomes stop separation during contraction by binding intermediate filaments, joining the cells together.hey occur at the Z line of the sarcomere and can be visualized easily when observing a longitudinal section of the tissue.
