Classified under:

Nouns denoting body parts

Hypernyms ("cardiac muscle" is a kind of...):

muscle; muscular tissue (animal tissue consisting predominantly of contractile cells)

Hyponyms (each of the following is a kind of "cardiac muscle"):

cardiac pacemaker; pacemaker; SA node; sinoatrial node (a specialized bit of heart tissue that controls the heartbeat)

papillary muscle (any of several muscles associated with the atrioventricular valves)

atrioventricular bundle; atrioventricular trunk; bundle of His; truncus atrioventricularis (a bundle of modified heart muscle that transmits the cardiac impulse from the atrioventricular node to the ventricles causing them to contract)

atrioventricular node (a node of specialized heart muscle located in the septal wall of the right atrium; receives impulses from the sinoatrial node and transmits them to atrioventricular bundle)

myocardium (the middle muscular layer of the heart wall)

Purkinje fiber (a specialized cardiac muscle fiber that is part of the Purkinje network)

Purkinje's system; Purkinje's tissue; Purkinje network (a network of Purkinje fibers that carry the cardiac impulse from the atrioventricular node to the ventricles of the heart and causes them to contract)

Holonyms ("cardiac muscle" is a part of...):

heart; pump; ticker (the hollow muscular organ located behind the sternum and between the lungs; its rhythmic contractions move the blood through the body)
