anatomy of upper limb

Reading File
Upper-limb anatomy can be studied in these connected sections:
  1. Osteology: clavicle, scapula, humerus, radius, ulna, carpals, metacarpals, phalanges
  2. Joints and movements: shoulder, elbow, radioulnar, wrist, hand joints
  3. Muscles and compartments: shoulder girdle, arm, forearm flexor and extensor groups, intrinsic hand muscles
  4. Nerves: brachial plexus, axillary, radial, median, ulnar, musculocutaneous nerves
  5. Arteries, veins, lymphatics: subclavian to axillary to brachial arteries, radial and ulnar arteries, superficial veins
  6. Surface anatomy and clinical correlations: pulse points, dermatomes, nerve injuries, common fractures, carpal tunnel syndrome
At a high level, the upper limb is attached to the trunk chiefly through the clavicle and scapula. Its function prioritizes mobility and hand precision. The brachial plexus supplies the limb, while arterial flow proceeds from the subclavian artery through axillary and brachial arteries to the radial and ulnar arteries in the forearm and hand.
