Human Skeletal Muscle Histology

Human skeletal muscle longitudinal section of muscle fibres showing sarcomeres. Stain HE magnification x40. See also full image

Sarcomere components

• A band - (anisotropic bands, light band) are composed of the thick myosin filaments.
• I band - (isotropic bands, light band) are composed of thin actin filaments.
• H band - (German, heller =brighter). are composed of the thick filaments that is not overlapped (superimposed) by the thin filaments.
• Z line - (German, Zwischenscheibe = Intermediate plate) appears as a series of dark lines between the I bands, indicate the end of one sarcomere and the beginning of the next.
