what structure on the lateral scapula does the humerus articulate with
To side a scapula, first locate the spine of the scapula (located on the posterior surface of the scapula). Next, locate the glenoid fossa (cavity) of the scapula. Since the glenoid fossa (cavity) articulates with the head of the humerus, it has to be located on the lateral surface of the scapula. So, to side a scapula...make sure the spine of the scapula is facing posteriorly and the glenoid fossa (cavity) is facing laterally.
