WebMyocytes are long, tubular cells. They develop from myoblasts to form muscles in a process called myogenesis. [2] There are various specialized forms of myocytes: cardiac, skeletal, and smooth muscle cells. They have different structures. The striated or striped cells of cardiac and skeletal muscles are called muscle fibers. [1] WebThe coordinated interaction of the myofilaments actin and myosin within the myocytes gives muscle tissue the ability to contract. Depending on the intracellular arrangement of these myofilaments, muscle tissue is classified as either striated (skeletal and cardiac) or nonstriated (smooth) muscle.
