Costal cartilages
The costal cartilages form part of the thoracic cage and anterior chest wall. There are ten costal cartilages bilaterally, one for each of the corresponding 1 to 10ribs, and each of the first seven ribs forms one of the seven costochondral joints.
Costal cartilages 1-7 articulate with the sternum at sternocostal joints, and costal cartilages 8-10 are attached to each other via small interchondral synovial joints forming the costal margin.
