Which is an action of the serratus anterior?

Question

Quizplus · Accepted Answer

The action of the serratus anterior is to protract (abduct) the scapula at the scapulocostal joint. This means that it pulls the scapula away from the spinal column, allowing the arm to reach forward and away from the body. Extension of the arm at the glenohumeral joint is mainly controlled by the triceps brachii muscle, while flexion of the arm at the glenohumeral joint is mainly controlled by the biceps brachii muscle. Retraction (adduction) of the scapula at the scapulocostal joint is mainly controlled by the rhomboid muscles.
