the scapula (shoulder blade) and the clavicle (collarbone) make up the pectoral girdle. Each upper limb articulates with the trunk at the pectoral girdle, or shoulder girdle The pectoral girdle consists of two broar, flat scapulae and the two slender, curved clavicles. Each clavicle articulates with the manubrium of the sternum; these are the only direct connections between the pectoral girdle and the axial skeleton. Skeletal muscles support and position each scapula, which has no bony or ligamentous connections to the thoracic cage.
