What is the difference between visceral and multiunit smooth muscle?
Just so, what is the difference between multi unit smooth muscle and single unit smooth muscle?
Single-unit smooth muscle produces slow, steady contractions that allow substances, such as food in the digestive tract, to move through the body. Multi-unit smooth muscle, the second type of smooth muscle observed, are composed of cells that rarely possess gap junctions, and thus are not electrically coupled.
Secondly, where is multiunit smooth muscle found? Most smooth muscle is of the single-unit variety, that is, either the whole muscle contracts or the whole muscle relaxes, but there is multiunit smooth muscle in the trachea, the large elastic arteries, and the iris of the eye.
In this way, how is multiunit smooth muscle like skeletal muscle?
Smooth muscle is so named because it has no visible striations. Smooth muscle is controlled by the autonomic nervous system, hormones, and intrinsic factors in the organ. Smooth muscle fibers are smaller and shorter than skeletal muscle fibers. Multiunit smooth muscle is primarily under neural control.
What is visceral smooth muscle?
Visceral muscle tissue, or smooth muscle, is tissue associated with the internal organs of the body, especially those in the abdominal cavity. There are three types of muscle in the body: skeletal, smooth, and cardiac.
