Can smooth muscle divide
Did you know?
WebUnlike other muscle, smooth muscle can also divide to produce more cells, a process called hyperplasia. This can most evidently be observed in the uterus at puberty, which responds to increased estrogen levels by producing more uterine smooth muscle fibers, and greatly increases the size of the myometrium. Previous Next Order a print copy WebObservations in vivo and in vitro demonstrate: 1) smooth muscle cells are capable of more than one function and can alter their phenotype/state accordingly (modulation); 2) in the majority of cases before a smooth muscle can divide it must modulate from a contractile to a synthetic phenotype; 3) modulation is reversible; 4) however, if synthetic state smooth …

WebMay 11, 2006 · Because the penis is compromised of 50 percent smooth muscle, and smooth muscle has a lot of the basic properties of skeletal muscle (the biceps, triceps, and all the other commonly known muscles), we can presume that it might react to stress the same way normal muscle does. Which is a no brainer for us all!
WebMay 17, 2024 · Cardiac muscle also demonstrates striations, the alternating pattern of dark A bands and light I bands attributed to the precise arrangement of the myofilaments and fibrils that are organized in sarcomeres along the length of the cell (Figure 17.3. 1 .a).
