			The sternum, according to Hanson's recent contribution, originates independently of the ribs. On each side, some distance from the midventral line, the sternal band or bar arises as a mesenchymal condensation in the body wall. These bars then approach the midventral line and fuse with each other to form a single cartilaginous structure. Meanwhile the ventral ends of the first seven ribs extend far enough to come into contact with and join the sternal bar (Fig. 130). Before the two bars have united a medial unpaired rudiment appears opposite their anterior ends to form the presternum with which the paired rudiments subsequently unite. The presternal component, with which the clavicles articulate, probably represents the ventral part of the primitive vertebrate shoulder girdle.
