Is the Heart a Muscle? Anatomy, Heart Conditions, and More
WebbCardiac muscle is made from cells called cardiocytes. Like skeletal muscle cells cardiocytes have a striated appearance, but their overall structure is shorter and thicker. Cardiocytes are branched, allowing them to connect with several other cardiocytes, forming a network that facilitates coordinated contraction.

WebbCardiac muscle contains actin, myosin, troponin C and tropomysin filaments and a T system located at the Z-lines (cf. p314). Cardiac Excitation – Contraction and Calcium. Like skeletal muscle, the link between electrical excitation and … WebbCardiac muscles: These striated muscles look similar to skeletal muscles. Special cells called cardiomyocytes make up the fibers in cardiac muscles. Cardiomyocytes help your heart beat. Smooth muscles: The proteins actin and myosin also make up smooth muscle fibers. In skeletal muscles, these proteins come together to form a spindle shape. Cardiac muscle (also called heart muscle or myocardium) is one of three types of vertebrate muscle tissues, with the other two being skeletal muscle and smooth muscle. It is an involuntary, striated muscle that constitutes the main tissue of the wall of the heart.
