Scapula of the Spine

The Scapula

The scapula (shoulder blade) forms part of the shoulder, at the back. It is a triangular, flattened bone, with several projections. The scapula is attached to the outer end of the collar bone (clavicle) at the acromioclavicular jooint. Its outer end provides a socket for the head of the upper arm bone (humerus), forming the bony articulation of the shoulder joint. The Scapula is held in place by strong muscles, which can move it in relation to the chest wall. It provides attachment for many of the muscles of the shoulder and upper arm, including the biceps.
