Sagot :

Final answer:

Intercalated discs in cardiac muscle facilitate coordinated contraction through gap junctions and desmosomes.


Explanation:

Intercalated discs are specialized structures found in cardiac muscle that contain gap junctions and desmosomes. These structures allow for coordinated contraction of cardiac muscle cells. Gap junctions facilitate the flow of ions between cells, enabling synchronized contraction, while desmosomes anchor the ends of muscle fibers together during contraction.
