Smooth muscle, also known as involuntary muscle, is a form of muscle that does not have cross stripes when viewed through a microscope. It is composed of thin spindly cells with a single nucleus in the center.
Smooth muscle tissue, as opposed to striated muscle, contracts gently and automatically. It makes up a large portion of the musculature of internal organs and the digestive system.
Smooth muscle fibers are organized into branching bundles. Unlike skeletal muscle fibers, these bundles are not perfectly parallel and ordered, but rather constitute a complex structure. As a result, the cells can contract with far greater force than striated muscle.
