Is an involuntary muscle that has the striated appearance of skeletal muscle with dark and light bands along the length of its fiber?

I believe the answer is Cardiac Muscle

Cardiac muscles tissues only occurs in the heart, where they constitutes the bulk of the heart walls They are striated like the skeletal muscle, however, the cardiac muscle is involuntary. It can and does by the nervous system. Most individuals have no conscious control of how fast heart beats.
