What it is
Smooth hyaline cartilage covering the articular surface of the humeral head.
Function
Lets the head glide in the glenoid with almost no friction.
Size
≈ 1–2 mm thick
Clinical note
The glenoid is only a third as large as the head, so the shoulder is the most commonly dislocated major joint.
