The unusual microscopic anatomy of a muscle cell gave rise to its terminology. The cytoplasm in a muscle cell is termed the sarcoplasm; the smooth endoplasmic reticulum of a muscle cell is termed the sarcoplasmic reticulum; and the cell membrane in a muscle cell is termed the sarcolemma. The sarcolemma receives and conducts stimuli. WebIn culture, myonuclei can be labelled with H3-thymidine and their ultimate fate, either as "free" myonuclei or myonuclei associated with disrupted myotubes can be followed unequivocally. Three types of experiments are performed: (i) Primary myogenic cultures containing only myotubes are subcultured. dianthus fruit punchWebTitin is a giant structural sarcomeric protein with a molecular weight of more than 3800 kD.
