Question

Quizplus · Accepted Answer

The short head of the biceps muscle primarily functions in elbow flexion and forearm supination. Therefore, a tear at its proximal attachment would most likely affect the ability to perform these movements. Shoulder flexion is primarily controlled by the deltoid muscle and is not directly affected by a tear to the short head of the biceps. Forearm pronation is primarily controlled by the pronator teres muscle, which is not directly affected by a tear to the short head of the biceps.
