Which type of vertebrae articulate with the ribs?

The thoracic vertebrae are specifically designed to articulate with the ribs, forming a crucial component of the ribcage that protects vital organs like the heart and lungs. Each of the twelve thoracic vertebrae has costal facets on its transverse processes and bodies, which create points of connection for the ribs. This anatomical feature allows for the ribcage to maintain a certain level of flexibility while providing essential support and stability.

In contrast, cervical vertebrae, which are located in the neck, do not articulate with the ribs at all. Lumbar vertebrae are situated in the lower back and similarly lack any connections to the ribcage. Finally, sacral vertebrae are fused together to form the sacrum and do not articulate with the ribs either. Thus, the unique structure and function of the thoracic vertebrae make them the correct choice in this context.
