BONES IN THE CHEST: THORACIC CAGE

Humans have 25 bones in the chest that together protects several vital organs and provide shape and structure to the upper body. These bones collectively form the thorax, one of the most critical structures in the human body.

Also known as the breastbone, the sternum is a flat bone located in the middle of the chest. Its primary function is protecting the heart. The sternum is the attachment point for the costal cartilage, which connects it directly to the first seven pairs of ribs.

STERNUM

The 12 pairs of ribs (24 in total) curve around the chest cavity to form the rib cage that protects the lungs, heart, and liver. There are seven pairs of true ribs, three pairs of false ribs and two pairs of floating ribs.

RIBS

Each rib consists of a head, neck, and tubercle.
