The general structure of skeletal muscle fiber The skeletal muscle fibers are generally slender cylindrical, with a diameter of 10~100 m, with a length of 1 to 40mm, the elder can reach 10cm, the two ends are blunt, and the tendon is connected with the tendon, and the end of some muscle fibers can be branched (the expressive and lingual muscles). Skeletal muscle fiber is a kind of multinuclear cell. The number of nucleus varies with the length of the muscle fiber, and the short nucleus is less; the number of the nucleus can reach 100 to 20O, and it is located below the muscularis membrane. The nucleus is oval, dyed light, and the nucleolus is clear. There are a large number of myofibrils (myofibril) parallel to their long diameters in the sarcoplasm of skeletal muscle fibers. The myofibrillar fibers were filamentous, and the diameter was about l to 2 mu m. Under the light microscope, each myofibril is made up of many bright and dark bands, all of the myofibrils are arranged in the same plane in neatly, so that the muscle fibers of the longitudinal section appear in the bright and dark lines, and in the myofibrils on the transverse section. Microstructural magnification model of ENOVO skeletal muscle fiber This fine model magnified about 40 thousand times the structure of skeletal muscle fibers, a long cylindrical muscle fiber, and a thin reticular fiber (RF) outsourced to the cells with coarser collagen fibers (CF) and capillary (Cap) anatomical features within the cell space. It can be explained very clearly with the help of this model.
