This diagram shows a sarcomere in the relaxed state. There are four, thick myosin filaments at the center of the sarcomere. The myosin filaments contain myosin heads on both of their ends. The ends of the myosin filaments overlap with actin filaments that protrude from both outer edges of the sarcomere. The H zone is the central region of the sarcomere where there are only myosin filaments. The A band contains the H zone and the areas where the ends of the myosin filaments overlap with the ends of the actin filaments. The I bands are the outermost areas of the sarcomere that contain only the actin filaments. Image Courtesy of 3DScience. com

How would the H-zone in a contracted sarcomere differ from that of a relaxed sarcomere?

The H-zone is narrower in a contracted sarcomere.
The H-zone is wider in a contracted sarcomere.
The H-zone is unchanged in a contracted sarcomere.
The H-zone contains both actin and myosin in a contracted sarcomere.
