CARDIAC MUSCLE

n. a specialized type of muscle found in the heart. It is composed of involuntary, striated muscles with branching fibers which interconnect with each other. This interlocking of cardiac fibers permits the rapid spread of action potentials, enabling heart muscle to contract rhythmically.

CARDIAC MUSCLE: "Cardiac muscle cannot be found elsewhere in the body but only in the heart."
