**Muscle Fiber Structure Diagram**

The image displays a detailed diagram of a muscle fiber, highlighting various regions within the sarcomere. The labeled sections (A, B, C, D, E, F, G, H) correspond to various parts of the sarcomeric structure.

- **A**: Denotes the entire length of the sarcomere, ranging from Z-line to Z-line.
- **B**: Marks the A-band, which appears darker due to the presence of thick filaments.
- **C**: Represents the H-zone, the lighter central part of the A-band where only thick filaments are present.
- **D**: Shows the I-band, which contains only thin filaments and appears lighter.
- **E**: Indicates the Z-line/disc, which anchors the thin filaments.
- **F, G, H**: Additional regions that may include the location of additional structural proteins or overlapping filament regions, though specific labels are not determined here.

**Exercise: Match the labeled structure with its name**

*Note: Not all choice names will be used for labeling.*

- Sarcomere: [ Choose ]
- I-Band: [ Choose ]
- A-Band: [ Choose ]
- H-Zone: [ Choose ]
