3D Anatomy of Upper Limb

The upper limb consists of four main regions: the shoulder, arm, forearm, and hand. The shoulder girdle connects the upper limb to the trunk and provides a wide range of movement. Comprising the clavicle and scapula, the shoulder girdle supports the humerus. The humerus, a long bone, extends from the shoulder to the elbow, where it articulates with the radius and ulna. The radius and ulna form the forearm, allowing for pronation and supination. The hand, including the wrist, metacarpals, and phalanges, facilitates complex movements and dexterity. Key structures include muscles, tendons, ligaments, and neurovascular bundles essential for function and mobility.
