vertebral differences

- Cervical vertebrae: Smallest vertebrae; have transverse foramina and often straight spinous processes.

- Thoracic vertebrae: Have costal facets for rib attachment and long, downward-pointing spinous processes.

- Lumbar vertebrae: Largest vertebrae; have thick bodies and short, blunt spinous processes to support body weight.
