Scapula
The proximal end of the scapula is considered the articular surface.

BU 22
SC S
Ventral portion of flat blade near proximal end identifiable by groove between tuber scapulae and glenoid cavity. Portion of anterior and posterior margins may be present. None of glenoid fossa present. Please note: the bold lines in the drawing indicate the area of BU which is on the reverse (ventral) face of the element. The one presented in the drawing is the dorsal view. (KK)
