Quizplus · Accepted Answer

The deltoid tuberosity is located on the lateral aspect of the humerus and serves as the insertion point for the deltoid muscle. The deltoid muscle is responsible for abducting the shoulder joint, which means moving the arm away from the body to the side. Therefore, muscles that insert into the deltoid tuberosity are most likely to abduct the shoulder.
