AHRQ’s CCSR groups this code into broader clinical categories.
Clinical InformationClinical
Clavicle
a bone on the ventral side of the shoulder girdle, which in humans is commonly called the collar bone.Costal Cartilage
bars of hyaline cartilage extending from the anterior ends of the upper ribs. they attach to the sternum directly or indirectly by connecting to upper costal cartilage that attaches to the sternum. costal cartilages extend the ribs anteriorly and contribute to the enhanced elasticity of the thoracic wall.Sternum
a long, narrow, and flat bone commonly known as breastbone occurring in the midsection of the anterior thoracic segment or chest region, which stabilizes the rib cage and serves as the point of origin for several muscles that move the arms, head, and neck.
