Scapula is a triangular, flat bone , lying in the upper back that connects the clavicle to the humerus. The scapula or shoulder blade is a flat, triangular upper limb bone that lies on the posterior surface of the thorax, over the ribs 2-7. It is a part of the pectoral (shoulder) girdle, together with the clavicle. The scapula articulates with the humerus, forming the shoulder (glenohumeral) joint. It also articulates with the clavicle via the acromioclavicular (AC) joint. This serial connection between these bones gives the scapula an important role in the mobility of the upper limb ... The scapula is also known as the shoulder blade . It articulates with the humerus at the glenohumeral joint, and with the clavicle at the acromioclavicular joint. In doing so, the scapula connects the upper limb to the trunk. The scapula connects the humerus with the clavicle and forms the back of the shoulder (pectoral) girdle. It is a flat triangular shaped bone located posterolaterally on the thoracic cage.
