Answer:
Cardiac muscles have intercalated disc that connects one cardiac muscle fibre to other.
Step-by-step explanation:
Intercalated discs are a characteristic feature of cardiac muscles. These structures connect one cardiac fiber to others. Intercalated discs have desmosomes and gap junctions.
The function of desmosomes of the intercalated disc is to hold the cardiac muscle fibers together while gap junctions serve to facilitate the rapid conduction of electrical signals.
