NEET PG DENTAL EXAM

Detailed explanation-1: -Intercalated discs are part of the cardiac muscle sarcolemma, so they also contain gap junctions for depolarization between muscle fibers and desmosomes that hold the fibers together during cardiac muscle contraction (Fig.

Detailed explanation-2: -Cardiac muscle fibers cells also are extensively branched and are connected to one another at their ends by intercalated discs. An intercalated disc allows the cardiac muscle cells to contract in a wave-like pattern so that the heart can work as a pump.

Detailed explanation-3: -Cardiac muscles contain intercalated discs and branching fibers. Intercalated discs support synchronized contraction of cardiac muscle tissue.
