- 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.

Nov 23, 2022 · The fibers are separated by collagenous tissue that supports the capillary network of cardiac tissue. The myofilaments of cardiac muscle are arranged in a similar pattern to skeletal muscle, resulting in cross-striations. The fibers are crossed by linear bands called intercalated discs.

How are cardiac fibers separated from skeletal muscle?
Cardiac muscle fibers have a single nucleus, are branched, and joined to one another by intercalated discs that contain gap junctions for depolarization between cells and desmosomes to hold the fibers together when the heart contracts.

Jul 30, 2023 · Cardiac muscle cells contain branched fibers connected via intercalated discs that contain gap junctions and desmosomes. These interconnections allow the cardiomyocytes to contract together synchronously to enable the heart to work as a pump.

Jul 27, 2022 · (a) Cardiac muscle cells have myofibrils composed of myofilaments arranged in sarcomeres, T tubules to transmit the impulse from the sarcolemma to the interior of the cell, numerous mitochondria for energy, and intercalated discs that are found at the junction of different cardiac muscle cells.
