Editing Scapula (section)

====Front or subscapular fossa====
The front of the scapula (also known as the costal or ventral surface) has a broad concavity called the '''subscapular fossa''', to which the [[subscapularis muscle]] attaches. The medial two-thirds of the fossa have 3 longitudinal oblique ridges, and another thick ridge adjoins the lateral border; they run outward and upward. The ridges give attachment to the tendinous insertions, and the surfaces between them to the fleshy fibers, of the subscapularis muscle. The lateral third of the fossa is smooth and covered by the fibers of this muscle.

At the upper part of the fossa is a transverse depression, where the bone appears to be bent on itself along a line at right angles to and passing through the center of the [[glenoid cavity]], forming a considerable angle, called the subscapular angle; this gives greater strength to the body of the bone by its arched form, while the summit of the arch serves to support the [[spine of scapula|spine]] and [[acromion]].

The costal surface superior of the scapula is the origin of 1st digitation for the serratus anterior origin.
