WebIt has been accepted that the force produced by a skeletal muscle myofibril depends on its cross-sectional area, but not on the number of active sarcomeres since they are arranged in series. Two of the important proteins are myosin, which forms the thick filament, and actin, which forms the thin filament. Myosin has a long, fibrous tail and a globular head, which binds to actin. The myosin head also binds to ATP, which is the source of energy for muscle movement.
