Which muscle is located in the shoulder?

Explanation:
Deltoid is the muscle that sits over the shoulder joint, giving that rounded contour of the shoulder. It wraps from the clavicle and scapula to the humerus, so it’s right where the arm meets the body. Its position and structure let it move the arm in several directions—abduction is the main action, with the anterior and posterior fibers aiding flexion/rotation and extension, respectively. The other muscles listed aren’t located primarily on the shoulder: pectoralis major sits in the chest, the trapezius in the upper back/neck, and the latissimus dorsi along the back and side. So the muscle located in the shoulder is the deltoid.
