Thesuperior surface is subcutaneous; the inferior surfacepresents an elevation known as the conoid tubercle, for THK SCAPULA. 109 the attachment of the coraco-acromial hgaments. Theposterior surface of the scapula above the spine formsthe supra-spinous fossa; the surface below the spine formsthe infra-spinous fossa; it is smooth, and serves for theorigin of the infra-spinatus muscle. The anterior sur-face is concave and shallow, and constitutes the venter ofthe scapula; it is crossed by two or three curved Fig. 51.—The Scapula, Anterior Surface. The subscapular muscle arises from the whole extent ofthis surface. The superior border is thin, concave, andpresents at its middle a notch,—the supra-scapular,—which is converted into a foramen by the transverse liga-ment; it transmits the supra-scapular nerve. Projectingfrom the outer portion of the superior border at its junc-tion with the base is the coracoid process, a strong, finger- 110 PRACTICAL ANATOMY. shaped process of bone which curves upward, forward,and outward above the glenoid cavity; it is rough, for theattachment of muscles and ligaments, and serves also fortlie protection of the shoulder-joint. The internal orvertebral border is the longest; it is slightly convex, andpresents two well-marked lips, anterior and posterior,the anterior giving attachment to the serratus magnusmuscle, the posterior to the supra- and infra- spinousmuscles. The external or axillary border is thick andstrong and corded in appearance; it is sligh
