WebSep 22, 2024 · 3) Increasing the sarcomere length slightly again removes any opposing actin filament overlap. Consequently, all the myosin heads can extend and pull the actin filament towards the M-line. This particular region of the length-tension relationship is known as the optimal length, as it is the length that allows the most amount of active tension. WebThe z line of the skeletal muscle is the functional end point of the sarcomere and is composed of the protein actin, also known as the thin filament. ... the thick filaments consist mainly of _____ protein and are anchored ate the _____ of the sarcomere. a. collagen/ M line b. actin/ Z disc c. myosin/ M line d. tropomyosin/ M line e. troponin ...
