Intercalated discs are specialized structures found in cardiac muscle tissue.
These discs are unique to cardiac muscle and are not found in skeletal or smooth muscle.
Intercalated discs contain gap junctions and desmosomes, which facilitate communication and adhesion between cardiac muscle cells.
Gap junctions within intercalated discs allow for the rapid transmission of electrical impulses, ensuring synchronized contraction of the heart muscle.
Desmosomes provide mechanical strength, preventing cardiac muscle cells from pulling apart during contraction.
