Explain the role of muscles in locomotion. Muscle cells are specialized for contraction. Muscles allow for motions such as walking, and they also facilitate bodily processes such as respiration and digestion. The body contains three types of muscle tissue: skeletal muscle, cardiac muscle, and smooth muscle (Figure 1). Figure 1.

Abstract. Although polyploid nuclei have long been known to be present in many adult human tissues, the ploidy of smooth muscle cells in human artery wall has never been determined. We measured DNA content in individual smooth muscle cell nuclei of artery wall specimens by two means: Feulgen microdensitometry and flow microfluorimetry.Skeletal Muscle Tissue. The striations are evidence of the myofilaments inside the muscle fibers. The position of the nuclei and vascularity are also signs of muscle tissue. You observe a tissue under a microscope. There appears to be a lumen on one side of the tissue.

Smooth Muscle Cells Smooth muscle fibers are long, spindle-shaped (fusiform) cells. Note the single and centrally placed nucleus in each smooth muscle cell. The absence of striation is also characteristic of the smooth muscle cells. How does the number and location of the nuclei in smooth muscle compare to that in striated muscle? Markers. The muscle stem cell is the defined as a mononuclear cell located in a unique position. In 1961, Dr. Mauro [] found mononuclear cells located between the basal lamina and sarcolemma (cell membrane of myofiber) in frog muscle and named them 'satellite cells.'As predicted by Dr. Mauro, MuSCs are indispensable for skeletal muscle regeneration [14, 15].An individual smooth muscle cell is very thin and tapers to its ends. Though not visible in this image, each cell has an oval nucleus in the center. The lower image shows smooth muscle layers of the intestinal wall. In the inner layer, the smooth muscle cells are cut in longitudinal section. The oval nuclei are stained purple. Abstract. Skeletal muscle cells are noteworthy for their syncytial nature, with each myofiber accumulating hundreds or thousands of nuclei derived from resident muscle stem cells (MuSCs). These nuclei are accrued through cell fusion, which is controlled by the two essential fusogens Myomaker and Myomerger that are transiently expressed within ...
