WebThe myofibril appears striated as they are composed of actin and myosin filaments, repeated in units called sarcomere, which is the basic functional unit of the muscle fiber. The sarcomere is responsible for the striated appearance of muscle.The actin is thin filament and myosin is thick filaments. A muscle fascicle is a bundle of skeletal ... WebThis central part of thick filament, not overlapped by thin filaments is called the ‘H’ zone. Hence H-zone in skeletal muscle fibre is due to Central gap between actin filaments extending through myosin filaments in A-band. So, the correct answer is 'Central gap between actin filaments extending through myosin filaments in A-band'.
