Question

Quizplus · Accepted Answer

Smooth muscle is responsible for movement within the gut, as well as in other organs such as blood vessels and the uterus. It uses a different contractile mechanism than skeletal muscle, but it still involves the sliding of filaments. Smooth muscle cells are typically mononucleate. The beating of the heart is controlled by cardiac muscle, which is also mononucleate but uses intercalated discs to connect cells.
