The pectoral girdle is made up of a left pectoral girdle and a right pectoral girdle. Each set of pectoral girdles has two bones, one clavicle and one scapula.
The clavicle bones on both the left and right pectoral girdles are articulated with the sternum. The clavicles are also found on the anterior or front part of the skeleton.
The scapula bones on both the left and right pectoral girdles are part of the posterior appendicular skeleton. The scapula bones each articulate with clavicle and the humerus.
Your pectorial girdle is located at your shoulder area on your appendicular skeleton. Your upper limb bones are attached to the pectoral (shoulder) girdle.

∙ 12y agoThe pectoralis major is the large fan like muscle located on either side of the chest, originating from the sternal half of the clavical, the anterior surface of the sternum, and the cartilage of the first seven ribs, and inserting in the bicepital groove of the humerus. Therefore, its primary actions deal with movements of the shoulder joint. It adducts, flexes, and medially rotates the humerus.
There is also a pectoralis minor, which is also located on the chest, but lies deep to the pectoralis major. It originates on ribs 3-5, and inserts on the coracoid process of the scapula. The pectoralis minor works on the scapula, drawing it toward the thorax so as to increase the range of motion of the shoulder.

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.
