STRUCTURE OF SKELETAL MUSCLE • Skeletal muscles are composed of clusters of muscle cells. WebbSkeletal muscle can be confused with dense regular connective tissue at low magnification (especially 40X). They stain the same color, and the skeletal muscle cell nuclei are flattened just like the fibroblast nuclei in …

WebbSkeletal muscle is made up of thousands of muscle fibres that run the length of the muscle. Each muscle fibre consists of many contractile units called myofibrils which run the length of each muscle fibre. Individual muscle fibres are wrapped with fascia and then further bound together by more fascia into bundles called fascicules. WebbPower athletes have a higher ratio of fast-twitch fibers (e.g., sprinters 70-75% type II), whereas for endurance athletes have more slow-twitch fibers (e.g., marathon/distance runners 70-80% type I) (2). Of course, muscle fiber type is not the only factor in an athlete’s success! There are plenty of other variables that take an athlete from ... field contact report
