**Figure Description:**
- **Figure 8.37**: Unknown vertebrae:
- **(A) Unknown vertebra 1**:
- The illustration shows a vertebra with broad wings and a large vertebral foramen, characteristic of a cervical vertebra, specifically the atlas. It has no vertebral body and the lateral masses are prominent, suggesting it supports the skull.
- **(B) Unknown vertebra 2**:
- This vertebra features a dense body and round vertebral foramen, with large transverse processes. This is typical of a lumbar vertebra, which is designed to bear more weight.
- **(C) Unknown vertebra 3**:
- The vertebra has a small body, long spinous process, and facets for rib attachment, indicating a thoracic vertebra. These features support connections with the ribs.
Students are encouraged to compare these characteristics with a standard anatomy reference to accurately classify each type.
