Thin and thick filaments are organized into repeating units called sarcomeres. Dark lines called Z-lines mark off the boundaries of each sarcomere. Thin filaments attach to the Z-lines at both ends of the sarcomere, while thick filaments are unattached. Each myofibril contains thousands of sarcomeres.
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. 4  I Bands are lighter areas of non-overlap between actin and myosin that contain the Z-lines.n views of this muscle type, striations are not as strong as those of skeletal muscle. Other structural features are usually apparent and of use for identification if the striations are weak. Due to constant activity cardiac muscle has a constant need for oxygen and glucose delivery.
