3D Anatomy of Upper Limb Muscles

Muscular anatomy of the upper limb encompasses a range of muscles responsible for movement and stabilization. The deltoid and rotator cuff muscles control shoulder movements. The arm contains major muscles such as the biceps brachii, triceps brachii, and brachialis, which facilitate elbow flexion and extension. The forearm’s flexor and extensor groups manage wrist and finger motions. Intrinsic muscles of the hand, including the thenar and hypothenar eminences, allow for fine motor skills. Detailed 3D models illustrate the origin, insertion, innervation, and function of each muscle.
