Myofibrils account for roughly 80% of cellular volume, and are the contractile elements of the muscle cell. Myofibrils consist of repeating units called sarcomeres (the contractile unit of the myofibril), which have overlapping myofilaments connected to Z discs at either end of the sarcomere.
In contrast to smooth muscle, cardiac and skeletal muscle types possess an internal ultrastructure of highly organized contractile myofilaments. Actin and myosin myofilaments are stacked and overlapped in regular repeating arrays to form sarcomeres.he A and I bands repeat along the length of the muscle fibers to create the striations visible under the light microscope. 1  Sarcomeres repeat along skeletal and cardiac fibers. 2  Components between adjacent Z-lines comprise the sarcomere. 3  Sarcomeres are considered the functional units of striated muscles.
