Study Notes
Articulation with Ribs
- The superior costal facet articulates with the inferior costal facet on the atypical (non-typical) thoracic vertebrae.
The Rib Structure
- The rib has a thin and fat shaft with internal and external surfaces.
- The superior margin is smooth and rounded, while the inferior margin is sharp.
- The shaft bends forward, just lateral to the tubercle, at an angle.
- The outer surface is rough, while the inner surface is smooth.
- The inferior margin of the internal surface has a distinct costal groove.
