The infraglenoid tubercle is the part of the scapula from which the long head of the triceps brachii muscle originates. The infraglenoid tubercle is a tubercle located on the lateral part of the scapula, inferior to (below) the glenoid cavity. The name infraglenoid tubercle refers to its location below the glenoid cavity.
Function[edit]
The infraglenoid tubercle is the origin of the long head of the triceps brachii muscle.[1][2] It helps to stabilise the muscle origin.[1]
