Smooth muscle is an involuntary non-striated muscle. It is divided into two subgroups; the single-unit (unitary) and multiunit smooth muscle. Within single-unit cells, the whole bundle or sheet contracts as a syncytium (i.e. a multinucleate mass of cytoplasm that is not separated into cells).mooth muscle is found within the walls of blood vessels (such smooth muscle specifically being termed vascular smooth muscle) such as in the tunica media layer of large (aorta) and small arteries, arterioles and veins.
Skeletal muscle tissue is found in our skeletal muscles; for example, the biceps. Cardiac muscle is found in our heart, and smooth muscle is found in our visceral, or hollow, organs-for example, blood vessels and intestines.All muscles contract as a result of interaction between special proteins within the myocytes.pecifically, we have three different types of muscle tissue, including skeletal, cardiac, and smooth. Each type of muscle is unique in terms of its structure and its function. Regardless of the specific type, all muscle serves the same general function, and that is support and movement.
