The clavicle is a paired long bone connecting the sternum to the scapula that functions to hold the upper limb away from the trunk, increasing its range of motion. Its structure is defined by a sternal end and an acromial end, a superior surface that is smooth and an inferior surface that is roughened with ligamentous attachment sites, and a distinctive medial-lateral curvature (convex anteriorly medially, concave anteriorly laterally) that together allow the bone's orientation and laterality to be determined from its surface anatomy. This is a topic in musculoskeletal/thoracic anatomy, specifically the osteology of the pectoral girdle.
