Which muscle adducts the scapula and downwardly rotates it?

Explanation:
Rhomboids are responsible for pulling the scapula toward the spine (adduction or retraction) and rotating the scapula downward. Their fibers attach from the vertebral column to the medial border of the scapula, so when they contract they draw the scapula medially and rotate it so the bottom tip moves downward. This combination—scapular retraction with downward rotation—is characteristic of the rhomboids and helps stabilize the shoulder blade. Other muscles may contribute to downward rotation or retraction in different contexts, but the rhomboids are the primary pair that achieve both actions together.
