Dark a band function
WebWhich type of muscles have alternate dark and light bands? Muscle tissue. Skeletal muscle consists of striated, alternating light and dark protein bands (Fig. 3.1). Are I bands light or dark? I-Band appears as light bands under the microscope. A-Band has a wide light zone called H zone (Henson’s zone) in the middle. WebJul 7, 2024 · The structure of the sarcomere is described with the dark and the light band. A bands (or anisotropic bands): It is also called the dark band and contains the whole thick filament (myosin). I bands (or isotropic bands): it is called the light band that contains only the thin filament (actin). The thin filament lies between the two thick filaments.
