Cardiac muscle

Cardiac myocytes have a single (occasionally two) central nucleus in the middle of the cell, and are joined to each other by intercalated disks (Eberth lines). Intercalated disks are end-to-end junctions between individual cardiac muscle cells, thus – unlike skeletal muscle – the cardiac muscle fiber consists of many mononucleated cells aligned end to end. These cells are much thinner and smaller than multinucleated skeletal muscle fibers. (Figure 72.) Cardiac muscle cells are commonly branched and have numerous large mitochondria. Cardiac muscle is also cross-striated, and sarcomeres are arranged similarly in cardiac and skeletal muscle.
