Detailed explanation-1: -muscle cells, unique junctions called intercalated discs (gap junctions) link the cells together and define their borders. Intercalated discs are the major portal for cardiac cell-to-cell communication, which is required for coordinated muscle contraction and maintenance of circulation.
Detailed explanation-2: -Abstract. Cardiac muscle cells are equipped with three distinct types of intercellular junction–gap junctions, “spot” desmosomes, and “sheet” desmosomes (or fasciae adherentes)–located in a specialized portion of the plasma membrane, the intercalated disk.
Detailed explanation-3: -Answer and Explanation: Intercalated discs are found in a. cardiac muscle. Intercalated discs are distinctive structures of the heart that connect and send electrical signals between the myocardial cells.
Detailed explanation-4: -Intercalated discs ensure that the cardiac muscle functions as a single and well-coordinated unit. They hold and bind the cardiac muscle cells through fascia adherens and desmosomes, and ensure that the contractile force is transmitted from one cardiac muscle cell to another.
