**Step-by-Step Solution:** 1. **Understanding the Sarcomere Structure**: The sarcomere is the basic functional unit of striated muscle fibers. It is composed of thick and thin filaments that are responsible for muscle contraction. 2. **Identifying the Components**: In the sarcomere, the thick filaments are primarily made of myosin, while the thin filaments are primarily made of actin. 3. **Locating the A Band**: The A band is a region within the sarcomere that appears dark under a microscope. It is located in the middle of the sarcomere and spans the length of the thick myosin filaments. ...
