Upper limb anatomy in 3D:
muscles and bones

The bones of the upper limb with the muscles of the shoulder, arm, forearm and hand.

The rotator cuff muscles, supraspinatus, infraspinatus, teres minor and subscapularis, stabilise the shoulder joint, while the deltoid abducts the arm. The anterior compartment of the arm contains the elbow flexors (biceps brachii, brachialis, coracobrachialis) and the posterior compartment the triceps brachii; the forearm muscles move the wrist and fingers.
