Name two muscles that contribute to scapular upward rotation.

Explanation:
Upward rotation of the scapula is what allows the arm to lift overhead, and it’s produced by muscles that tilt the glenoid fossa upward. The serratus anterior is the primary upward rotator, pulling the medial border of the scapula forward and rotating the scapula so the glenoid faces upward. The upper trapezius adds to this motion by elevating the scapula and clavicle, helping rotate the scapula upward as the arm rises. Together, these two muscles provide the most effective and common combination for upward rotation. The other muscles listed either don’t rotate upward, or don’t contribute as a primary pair for this movement.
