The brachialis muscle is the primary flexor of the elbow, and its action is unaffected by the position of the forearm (pronation or supination) or the position of the shoulder. This is because its insertion and origin are both on the humerus and ulna, respectively, not crossing the shoulder or affected by forearm rotation.
