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 · Cardiac muscle fibers are long, branched cells, shaped like cylinders joined end-to-end, with one or two nuclei located centrally. The fibers are separated by collagenous tissue that supports the capillary network of cardiac tissue.

Cardiac muscle cells, or cardiomyocytes, are elongated and spindle-shaped, with one to two centrally located nuclei. These cell fibers are arranged in a branching network and intercalated discs, which are junctions that allow these muscle cells to contract in synchronization.
