WebA) Smooth muscle, in contrast to skeletal muscle, cannot synthesize or secrete any connective tissue elements. B) Smooth muscle cannot stretch as much as skeletal muscle. C) Certain smooth muscle cells can actually divide to increase their numbers. WebSmooth muscle contraction relies on the presence of Ca++ ions similar to skeletal and cardiac muscle. However, smooth muscle fibers are much smaller in all dimensions than skeletal muscle cells. T-tubules are not required to reach the interior of the cell and …
