Question

Quizplus · Accepted Answer

Upward rotation of the scapula involves the glenoid fossa moving superiorly and laterally, which would result in the superior movement of the glenoid fossa at the scapulocostal joint. Elevation would move the scapula superiorly, but it does not involve rotation of the scapula, so it would not necessarily result in superior movement of the glenoid fossa. Protraction involves the scapula moving away from the midline of the body, while upward tilt involves the scapula tilting upward, neither of which would result in superior movement of the glenoid fossa.
