Quizplus · Accepted Answer

The light band that contains thin filaments only is known as the I-band. It is named I-band because it is isotropic to polarized light. In a sarcomere, the A-band represents the dark band that contains both thick and thin filaments, the M-line represents the middle of the sarcomere where the myosin filaments are anchored, the Z-line represents the end of the sarcomere where the thin filaments are anchored, and the H-zone is the center of the A-band where there are only thick filaments.
