Identify the anatomical structure

Using the Thoracic Cage Anatomy knowledge point
The human thoracic cage, or rib cage, is a bony structure that encloses and protects the thoracic cavity, housing vital organs such as the heart and lungs.

Determine the number of rib pairs

Using the Rib Classification knowledge point
Humans typically possess 12 pairs of ribs, making a total of 24 ribs. These are classified into true ribs (pairs 1–7), false ribs (pairs 8–10), and floating ribs (pairs 11–12).
