| cardiac muscle |
the muscle of the heart, comprising the chief component of the myocardium and lining the walls of the large vessels joined to the heart; it is composed of fibers of striated but involuntary muscle. The composition and organization of its fibers resemble those of skeletal muscle, but instead of forming a syncytium, its branched, mononucleate cells are linked end to end by intercalated disks that provide both mechanical and ionic coupling for coordination of the entire muscle.
