Cardiac muscle

Cardiac muscle is found only in the muscle of the heart. It is striated like voluntary muscle. But it differs in that its fibers branch and anastomose with each other; they are arranged longitudinally as in striated muscle, are characteristically red in colour and not controlled by the will.

    Cardiac muscles possesses the special property of automatic rhythmical contraction independent of its verves supply. This function is described as myogenic as distinct from neurogenic. Normally the action of the heart is controlled by its nerve supply.
