Examine a clavicle: either a picture or a model from the classroom. How would you describe the differences in the sternal and acromial ends?
The scapula is a roughly triangular-shaped bone with a flattened body and three edges: the vertebral (medial) border, the axillary (lateral) border, and the superior border (Figure 8-2 ). A prominent ridge running along the dorsal surface of the bone toward the superior end is known as the spine and is very helpful for siding. Two major projections are the acromion at the end of the scapular spine, which is where the lateral end of the clavicle attaches, and the coracoid process, which is an attachment point for muscles of the upper arm. Another prominent landmark is the glenoid fossa (or cavity), a shallow socket that attaches to the humerus to create the shoulder joint.
