Definition

The appearance of the striated muscle is created by a pattern of alternating dark A bands and light I bands. A bands comprise thick filaments of myosin and proteins that bind myosin. They are bisected by the H zone, a paler region where the thick and the thin filaments do not overlap. The exact center of the A band is termed the M line.
