The myosin heads form cross bridges with the actin myofilaments; this is where they carry out a 'rowing' action along the actin. When the muscle fibre is relaxed (before contraction), the myosin head has ADP and phosphate bound to it. When a nerve impulse arrives, Ca ions cause troponin to change shape; this moves the troponin + tropomyosin complex away, leaving the myosin binding … WebEach myofibril is composed of two types of contractile filaments; Thin or Light filaments; Thick or Dark filaments; The number of these filaments varies in individual myofibrils. … WebA myofibril is composed of many sarcomeres running along its length, and as the sarcomeres individually contract, the myofibrils and muscle cells shorten (Figure 19.35). ...
