Detailed explanation-1: -myofibril, muscle fiber, filament, fascicle.
Detailed explanation-2: -In conclusion, the correct order of muscle structures is muscle, fascicles, fibers, myofibrils, and sarcomeres, from largest to smallest.
Detailed explanation-3: -Microscopic level-sarcomere and myofibrils. Cell level-myoblasts and myofibers. Tissue level-neuromuscular junctions and fascicles. Organ level-major skeletal muscles of the body.
Detailed explanation-4: -Skeletal Muscle Fiber Structure. Each skeletal muscle fiber is a skeletal muscle cell. These cells are incredibly large, with diameters of up to 100 µm and lengths of up to 30 cm. The plasma membrane of a skeletal muscle fiber is called the sarcolemma.
Detailed explanation-5: -The smallest contractile unit of skeletal muscle is the muscle fiber or myofiber, which is a long cylindrical cell that contains many nuclei, mitochondria, and sarcomeres (Figure 1) [58]. Each muscle fiber is surrounded by a thin layer of connective tissue called the endomysium.
