Skeletal Muscle & Muscular Dystrophy : A Visual Approach (Colloquium Series on the Cell Biology of Medicine)

Histologically, muscle is conveniently divided into two groups, striated and nonstriated, based on whether the cells exhibit cross-striations in the light microscope. Smooth muscle is involuntary: its contraction is controlled by the autonomic nervous system. Striated muscle includes both cardiac (involuntary) and skeletal (voluntary).
