Document Summary

Pectoral girdle - the bony ring, incomplete posteriorly, formed by the scapulae and clavicles, which is completed anteriorly by the manubrium of the sternum: it is supported by axio-appendicular muscles. Arm the part between the shoulder and elbow containing the humerus. Forearm the part between elbow and wrist containing the ulna and radius. Hand the part of the upper limb distal to the forearm containing the carpus, metacarpus, and phalanges. A doubly curved long bone, 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. Scapula: a triangular at bone, it lies on the posterolateral aspect of the thorax, overlying 2nd through. Exed: posterior aspect: olecranon fossa accommodates the olecranon of the ulna during full extension, epicondyles, trochlea, capitulum, olecranon, coronoid, and radial fossae, make up the condyle of the humerus, the condyle has two articular surfaces.
