Identify the anatomical classifications of ribs

Using the Thoracic Cage Anatomy knowledge point

The human thoracic cage contains 12 pairs of ribs, which are anatomically classified into three distinct structural groups based on their anterior attachment to the sternum:

• True ribs (vertebrosternal ribs, pairs 1–7): Attach directly to the sternum via their own costal cartilages.
• False ribs (vertebrochondral ribs, pairs 8–10): Attach indirectly to the sternum; their costal cartilages fuse with the cartilage of the rib immediately superior.
• Floating ribs (vertebral ribs, pairs 11–12): Have no anterior attachment to the sternum or other cartilages; they end within the abdominal wall musculature.

"Meat ribs" is a culinary term rather than an anatomical classification.
