Levator scapulae action includes elevating the scapula. Which concurrent motion does it perform?

• A. Elevates the scapula and rotates it inferiorly
• B. Depresses the scapula
• C. Protracts the scapula
• D. Retracts the scapula

Answer: (A)

Levator scapulae mainly elevates the scapula, and it also causes downward (inferior) rotation of the scapula. This means as it lifts the shoulder blade, it twists the scapula so the glenoid cavity faces slightly downward, helping position the arm for overhead or reaching activities while keeping the shoulder aligned. It does not depress, protract, or retract the scapula—those actions are produced by other muscles like pectoralis minor, serratus anterior, and the rhomboids/middle trapezius, respectively.
