The portion above the spine is called the supraspinous fossa, and that below it the infraspinous fossa . The two fossae are connected by the spinoglenoid notch, situated lateral to the root of the spine . </P> <Ul> <Li> The supraspinous fossa, the smaller of the two, is concave, smooth, and broader at its vertebral than at its humeral end; its medial two - thirds give origin to the Supraspinatus . </Li> <Li> The infraspinous fossa is much larger than the preceding; toward its vertebral margin a shallow concavity is seen at its upper part; its center presents a prominent convexity, while near the axillary border is a deep groove which runs from the upper toward the lower part . The medial two - thirds of the fossa give origin to the Infraspinatus; the lateral third is covered by this muscle . </Li> </Ul>

The anterior surface of the scapula is referred to as the
