Mirroring findings in rodents, average fiber (Types I and ...Muscle tension depends on: Number of motor units recruited. Degree of muscle stretch. Relative size of the muscle fibers - the bulkier the muscle fiber (greater cross-sectional area), the greater its strength. Recruitment also helps provide smooth muscle action rather than jerky movements.Skeletal muscle tissue develops through the fusion of individual myoblasts, or early muscle cells. This fusion results in a characteristic multinucleated structure. Because the cells are fused and multinucleated, they form a structural syncytium. Nuclei of skeletal muscle tissue are oval-shaped and located at the periphery of the cell.Figure 15.3.2 15.3. 2: Muscle type 1) Skeletal muscle cells are long tubular cells with striations (3) and multiple nuclei (4).
