Which muscles are the primary elevators of the scapula, with assistance from rhomboids?

• A. Lower trapezius and serratus anterior
• B. Pectoralis minor and latissimus dorsi
• C. Upper trapezius and levator scapulae
• D. Rhomboids

Answer: (C)

Raising the scapula mainly comes from lifting actions at the top of the shoulder girdle. The upper trapezius pulls the lateral part of the scapula upward, and the levator scapulae pulls the superior angle of the scapula upward as well. Together, they elevate the scapula to allow the arm to move overhead. The rhomboids, meanwhile, are best known for retracting the scapula toward the spine and downwardly rotating it; they stabilize the shoulder girdle and help control positioning during elevation, but they do not provide the primary lifting force. The other muscle pairs either depress, protract, or retract the scapula without producing the main elevation.
