How are smooth muscle cells arranged
WebThe molecular structure of the smooth muscle of myometrium is very similar to that of smooth muscle in other sites of the body, with myosin and actin being the predominant proteins. In uterine smooth muscle, there is approximately 6-fold more actin than myosin. A shift in the myosin expression of the uterine smooth muscle may be responsible for … WebA single smooth muscle fiber is thirty to two hundred micrometers long, thick centered and tapered at the ends. These smooth muscle fibers have a single nucleus that is centrally located and oval in shape. Smooth muscle fiber contains thick filaments and thin filaments. These filaments are in ratios of 1:10 and 1:15, but are not
