In anatomy, the scapula (Medical Latin), or shoulder blade, is the bone that connects the humerus (upper arm bone) with the clavicle (collar bone).
The scapula forms the posterior (back) located part of the shoulder girdle. In humans, it is a flat bone, roughly triangular in shape, placed on a posterolateral aspect of the thoracic cage.
