Costal cartilage

Other Terms: Costal cartilage of rib, Cartilago costalis, Cartilage costal


In general, costal cartilages are hyaline cartilage extensions from the anterior end of the ribs. The first 7 cartilages are flattened bars that connect the ribs to the sternum and are referred to as the costal cartilages of the true ribs. The 8th, 9th, and 10th costal cartilages each attach to the inferior margin of the cartilage above. These cartilages are referred to as the cartilages of the false ribs. The last two costal cartilages form small pointed projections that end in the body wall. The 11th and 12th ribs with their associated cartilages are called the floating ribs.
