Which tubercle lies under the glenoid cavity?

Explanation:
The landmark located beneath the glenoid cavity is the infraglenoid tubercle. This small projection sits just below the glenoid fossa and serves as the attachment point for the long head of the triceps brachii. The supraglenoid tubercle, in contrast, is above the glenoid cavity and marks the origin for the long head of the biceps brachii. The infraglenoid crest is a crest at the inferior rim rather than a tubercle, and the glenoid tubercle is a different projection at the rim. So, the infraglenoid tubercle is the one under the glenoid cavity.
