Overview

The pectoral girdle serves as the point of attachment for the upper limbs. It is comprised of two bones, the clavicle and scapula. The bone that articulates with the pectoral girdle is called the humerus. When these two join together this forms the glenohumeral joint. It is imperative you are not only able to identify the clavicles, scapulae, and their landmarks but that you get your orientation correct. Making a simple mistake such as not knowing the difference between anterior and posterior on the scapula can cost you a lot not only on a test but in medicine overall.
