Composite image illustrating the hierarchical organization of skeletal muscle. The top panel shows a whole muscle composed of multiple fascicles. The second panel displays a fascicle or fiber bundle, consisting of numerous myofibers. To the right, an individual myofiber is shown in detail, followed by a myofibril composed of repeating sarcomeres. At the bottom, a close-up of a sarcomere reveals the arrangement of myofilaments. The image demonstrates the structural levels from whole muscle to sarcomere.
