responsible for the rhythmic contractions of the heart.
The type of striated muscle tissue that forms the muscles of the heart.
the involuntary muscle found in the heart; contains actin and myosin filaments.
Specialized form of striated muscle found in the heart, consisting of individual heart muscle cells linked together by cell junctions.
Form of muscle fibres found in heart; has specific structural and functional properties adapted to the role of the heart as a pump.
striated, involuntary muscle that is found only in the heart.
the muscle tissue of the heart; adapted to continued rhythmic contraction
(KAWR-dee-ahk MUS-ehl) One of three types of muscle tissue. It is characterized by striations and involuntary contractions, and makes up the bulk of the heart wall.
Specialized heart muscles characterized by the presence of striated myofibrils, but differing from skeletal muscle in that myofibers contain internal nuclei, are branched, and are joined together at their ends by electron dense intercalated discs.
A type of muscle that forms the contractile wall of the heart; its cells are joined by intercalated discs that relay each heartbeat.
The type of muscle that is found in the walls of the heart. Cardiac muscle is striated but branched, unlike the straight-shaped striated skeletal muscle cells. PICTURE
A special kind of muscle found only in the heart. See also smooth muscle, striate muscle.
Cardiac muscle is a type of involuntary mononucleated, or uninucleated, striated muscle found exclusively within the heart. Its function is to "pump" blood through the circulatory system by contracting.
