Pectoral girdle: the boney ring, incomplete posteriorly, formed by the scapulae and clavicles, which is completed anteriorly by the manubriuim of the sternum. Arm is the part between the shoulder and elbow containing the humerus. Forearm is the part between the elbow and wrist containing the ulna and radius. Hand is the part of the upper limb distal to the forearm containing the carpus, metacarpus, and phalanges. Clavicle is a doubly curved long bone and has two ends. Sternal end articulates with the manubrium of the sternum at the sternoclavicular joint. Lateral end or acrominal end articulates with the acromion of the scapula at the acromioclavicular joint. * connects the upper limb to the trunk. * serves as a strut from which the scapula and free limb are suspended. * transmits shocks from the upper limb to the axial skeleton. Sternal facet articulates with manubrium of the sternum to form sternoclavicular joint.
