Cardiac muscles are involuntary muscles. They are involved in continuous rhythmic contraction and relaxation.

Cardiomyocytes or the cardiac cells are uninucleate, cylindrical, and elongated.

Cardiac muscles are found in heart. Characteristics of cardiac muscles are (any three):

  • The muscles have striations just like skeletal muscles by having actin and myosin filaments that are arranged into sarcomeres.

  • The muscles have an involuntary function as their functioning is not under our control.

  • The muscles are myogenic - means the contractions are generated within the muscles.

  • The muscles consist of a network of interconnected muscle fibres each of which has numerous mitochondria, myofibrils with sarcomere and many nuclei.

  • The muscle tissue has no regenerative capacity.
