Two major muscles, the deltoid and trapezius, attach to the acromion. The deltoid, which abducts the arm at the shoulder, forms its origin along the acromion, the spine of the scapula, and the clavicle. From these origins, it crosses the shoulder joint and inserts on the deltoid tuberosity of the humerus.
