Smooth muscle (so-named because the cells do not have striations) is present in the walls of hollow organs like the urinary bladder, uterus, stomach, intestines, and in the walls of passageways, such as the arteries and veins of the circulatory system, and the tracts of the respiratory, urinary, and reproductive systems (Figure \(\PageIndex{1}\).a,b).

All muscle cells originate from the: actin and myosin. Muscle tissue differentiate by cell lengthening with active synthesis of the proteins: skeletal, cardiac, smooth. The three types of muscle tissue are: Skeletal muscle. This type of muscle contains bundles of very long, multinucleated cells with cross-striations.Cardiac muscle cells are much smaller (10-20 μm in diameter and 50-100 μm in length) in comparison to skeletal muscle cells. Also unique to the cardiac muscle are intercalated discs that connect cardiac muscle cells to each other. Intercalated discs contain desmosomes and gap junctions, which perform important functions.A smooth muscle cell is a spindle-shaped myocyte with a wide middle and tapering ends, and a single nucleus. Like striated muscle, smooth muscle can tense and relax. In the relaxed state, each cell is 30–200 micrometers in length, some thousands of times shorter than a skeletal muscle cell. [1]Muscles attach to bones directly or through tendons or aponeuroses. Skeletal muscles maintain posture, stabilize joints, support organs, control internal movement, and generate heat.
