There are twelve pairs of ribs in the body. They are paired. The first rib and the 11th and 12th ribs are atypical. The first seven ribs are said to be true ribs, while the remaining five are false. The last two are floating ribs.

Typical ribs all have shafts, which project posteriorly and anteriorly. The shafts carry the angles (posterior or anterior angles).

Other parts of the rib include head, which may carry two facets, neck and tubercle (which includes articular and non-articular parts). It is these last features that distinguish the ribs.

Costal cartilages

Ribs have their anterior extremities replaced with Costal cartilages which reach the sternum and articulate with it. The costal cartilages costal cartilages are found in all ribs and they reach the sternum except in the 11th and 12th ribs. The first seven costal cartilages reach the sternum directly, while the 8th, 9th and 10th articulate with the lower aspect of the cartilage above.
