On the lateral angle of the scapula is a shallow pyriform, articular surface, the glenoid cavity (or glenoid fossa of scapula from Greek: "gléne", "socket"), which is directed lateralward and forward and articulates with the head of the humerus; it is broader below than above and its vertical diameter is the longest.

The surface is covered with cartilage in the fresh state; and its margins, slightly raised, give attachment to a fibrocartilaginous structure, the glenoid labrum, which deepens the cavity.
