What is the action of rhomboid minor?

Explanation:
Rhomboid minor mainly pulls the scapula toward the spine (retraction) and, because of its position along the medial border, it also causes the scapula to rotate downward and helps hold it flat against the thoracic wall. That combination—retraction with downward rotation and stabilization—fits the muscle’s orientation and how its fibers pull on the scapula. Other actions listed belong to different muscles: elevating the scapula is a primary job of the levator scapulae; depressing the scapula is done by muscles like pectoralis minor and gravity; protracting the scapula is the action of serratus anterior. So the description of retracting and downwardly rotating the scapula with stabilization best captures what rhomboid minor does.
