Ribs

There are 12 pairs of ribs in the human ribcage. The top seven pairs of ribs attached to the sternum with cartilage are called the true ribs. The bottom five pairs are called false ribs because they do not connect directly to the sternum. The final two pairs of ribs are called floating ribs because they do not connect to the sternum. The rib cage is responsible for protecting other organs in the chest. [CG] {NR}
