. Cunningham's Text-book of anatomy. Anatomy. Tuberositas coracoidea Fig. 184.—The Right Clavicle seen from above. sterno-clavicular articulation, is sharp and well denned, except below where it is rounded. The shaft exhibits a double curve, being bent forwards in the medial two- thirds of its extent, whilst in its lateral third it displays a backward curve. Of rounded or prismatic form towards its sternal end, it becomes compressed and flattened at its acromial extremity. It may be described as possessing two surfaces, a superior and an inferior, separated by anterior and posterior borders, which are well defined towards the lateral extremity of the bone, but become wider and less well marked medially where they conform more to the cylindrical shape of the bone. The superior surface, which is smooth and subcutaneous throughout its whole length, is directed upwards and for- wards. The anterior border, which separates the superior from the inferior surface in front, is rough and tubercular towards its medial end for the attachment of the clavicular fibres of the pectoralis major, whilst laterally, where it becomes continuous with the anterior margin of the acromial end, it is better defined, and bears the imprint of the origin of the fibres of the deltoid muscle; here, not uncommonly, a projecting spur of bone, called the deltoid tubercle, may be seen. The 'posterior border is broad medially,. Fig. 185. -The Upper Surface of the Right Clavicle with Muscle Attachments. Acromial articular SURFACE.
