Q

Why does cardiac muscle tissue have intercalated discs?

A

Cardiac Muscle cells are not “fused” together, and intercalated discs (gap junctions) link the cells together and define their borders. Also, Intercalated discs are the major way cardiac cells communicate with each other , which is required for coordinated muscle contraction and maintenance of circulation.
