The subscapular fossa shows in its lower half a number of branching vascular impressions, which mark the course of branches of the subscapular artery. The anterior edge of the bone is also appropriately termed the coracoid edge, since it is terminated inferiorly by the coracoid process. In its upper half this edge is convex, blunt, and rough, but in its lower half it is thin, smooth, and concave. The posterior edge, also called the glenoid edge, because it conducts at its lower end to the glenoid cavity, is slightly concave. At its extreme Fig. 63.--Eight Scapula Of Horse (Outer Surface). 1.

Several muscles of the shoulder take origin from this edge. The superior or vertebral edge carries the cartilage Of prolongation. This is a thin flexible plate of cartilage representing a persistent or unossified part of the foetal cartilaginous scapula. The cartilage is smooth and conxex on its upper free f edge, and posteriorly it forms a rounded projection which extends beyond the line of the posterior edge of the scapula. The inner surface of the cartilage gives attachment to the rhomboideus muscle. The cervical angle of the scapula, which sepa...
