Anterior surface or venter. cavity downward and backward to the internal border, about an inch above the inferior angle. The ridge serves for the attachment of a strong aponeurosis which separates the Infraspinatus from the two Teres muscles. The surface of bone between this line and the axillary border is narrow in the upper two-thirds of its extent, and traversed near its centre by a groove for the passage of the dorsalis scapulae vessels; it affords origin to the Teres minor muscle. Its lower third.
