WebIt is formed by the fusion of multiple myoblasts, and thereby acquires multiple cell nuclei. The nuclei are in the middle of the myotube cell, unlike the mature muscle fiber where the nuclei are at the periphery of the cell. A myotube has a tubular form instead of the more typical rounded cell form of the myoblast. WebSkeletal muscle fibers are larger with multiple, peripherally located nuclei. 1000x. Connective tissue Smooth muscle fibers and skeletal muscle fibers occur together in the middle part of the esophagus. In this field, compare the size of the fibers and location of the nuclei for these two muscle types. ...

WebSkeletal muscle cells are long cylindrical cells with many peripherally located nuclei per cell. Cardiac cells have one (or two) centrally located nuclei per cell; their branched ends fit together at tight junctions called intercalated discs, which are not seen in skeletal muscle Intercalated Discs Striations Nucleus of Cardiac Fiber WebThe NPCs did not exhibit any morphological changes or motor neuron differentiation; instead, they deteriorated and died. (B) A representative image of phalloidin-DAPI-stained human myoblasts showed normal morphology and differentiation features with centrally and peripherally located nuclei.
