Smooth Muscle

Smooth muscle (below) has short tapered (fusiform) cells with a central nucleus and it is found surrounding hollow internal organs such as the stomach, intestines, blood vessels and the urinary bladder. Smooth muscle also forms circular passageways called sphincters that control the flow of a fluid. While smooth muscle has myosin and actin, the protein fibers are arranged somewhat differently than in the other 2 types of muscle; therefore, smooth muscle lacks striations.

2 of theses slides were taken by students and the rest by me. They show smooth muscle in different organs. Scroll through the slides. Select one and draw it.
