Which muscle acts as an assistant to scapular elevation along with the primary elevators?

• A. Pectoralis minor
• B. Latissimus dorsi
• C. Serratus anterior
• D. Rhomboids

Answer: (D)

Scapular elevation is achieved when the shoulder blade is pulled upward toward the ear, with the main elevators being the upper fibers of the trapezius and the levator scapulae. The rhomboids contribute by pulling the scapula toward the spine and, as the scapula is stabilized in that position during overhead movements, they help lift the medial edge and support the elevated position. This supportive role is why they’re the best match among the choices for assisting elevation alongside the primary elevators. The other muscles don’t provide this upward-stabilizing action: pectoralis minor depresses the scapula and tilts it forward, serratus anterior protracts and upwardly rotates rather than elevating, and latissimus dorsi tends to depress or downwardly rotate the scapula during arm movement.
