Its upper surface is rounded and marked by three flat impressions.

• the highest of these gives ("superior facet") insertion to the Supraspinatus
• the middle ("middle facet") to the Infraspinatus.
• the lowest one ("inferior facet"), and the body of the bone for about 2.5 cm. below it, to the Teres minor.

Between the greater tubercle and the lesser tubercle is the intertubercular sulcus (bicipital groove).
