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.
The posterior portion of the pectoral girdle is the scapula, also known as the shoulder blade. It articulates with the clavicle at the acromioclavicular joint and connects the upper arm bone (humerus) to the axial skeleton. The scapula provides attachment points for various muscles involved in shoulder movement.
The pectoral girdle (shoulder girdle) consists of two bones, the scapula and clavicle. The clavicle (collarbone) is an S-shaped bone located on the anterior side of the shoulder while the scapula (shoulder blade) lies on the posterior side of the shoulder.
