Which muscle lifts the arm away from the body?

Explanation:
This movement is shoulder abduction—the arm is lifted away from the body. The deltoid muscle, covering the shoulder, is the main muscle responsible for this action. Its middle fibers specifically drive the arm outward from the trunk, with the front and back fibers assisting as the arm moves higher. (The initial phase of abduction is started by a different muscle, but the deltoid powers the lifting as the arm continues to rise.) The other options are muscles of the face or scalp and do not move the arm: the orbicularis oculi closes the eye, the corrugator furrows the brow, and the occipitalis pulls the scalp back.
