Which muscle inserts on the superior angle and medial border of the scapula?

• A. Latissimus dorsi
• B. Levator scapulae
• C. Trapezius
• D. Rhomboid minor

Answer: (B)

Think about where each muscle attaches to the scapula, because insertion points strongly determine their action. The muscle that reaches the superior angle and the medial border of the scapula is levator scapulae. That placement lets it lift the scapula and help stabilize it during neck and shoulder movements. The other muscles attach elsewhere: latissimus dorsi goes to the humerus, trapezius attaches to the spine of the scapula, acromion, and clavicle, and rhomboid minor attaches to the medial border near the spine rather than at the superior angle. So the unique insertion on the superior angle and medial border points to levator scapulae.
