. Smooth muscle cells have different diameters when cut in cross section because of their spindle-shape. This allows for coordinated contraction of many cells at once. The connective tissue sheath covering each fasciculus is known as perimysium, and the innermost sheath surrounding individual muscle fiber is known as endomysium. There are three types of muscle tissue: skeletal muscle, cardiac muscle, and smooth muscle. Unlike a fossil skeleton, however, your skeleton is a structure of living tissue that grows, repairs, and renews itself.
