The openings of the digestive and urinary tracts are encircled by skeletal muscles. These muscles provide conscious control over swallowing, defecation, and urination. 3.The basic units of skeletal muscle are muscle cells that have many nuclei. These muscle cells also contain light and dark stripes called striations. The striations are a result of the orientation of the contractile proteins inside the cells.
