Arm
Nerve supply to left coracobrachialis, biceps and brachialis muscles, medial view
The muscles have been retracted to show the course of the musculocutaneous nerve.
  1. Radial nerve
  2. Vertebral margin of scapula
  3. Teres major muscle
  4. Thoracodorsal artery
  5. Latissimus dorsi muscle (tendon of insertion)
  6. Triceps brachii muscle
  7. Superior ulnar collateral artery
  8. Ulnar nerve
  9. Medial intermuscular septum
  10. Median nerve
  11. Brachial artery
  12. Joint of humerus
  13. Middle cord of brachial plexus
  14. Upper pointer: Musculocutaneous nerve Lower pointer: Branches of musculocutaneous nerve (to coracobrachialis muscle)
  15. Lateral head of median nerve
  16. Posterior circumflex artery of humerus
  17. Coracobrachialis muscle
  18. Medial head of median nerve
  19. Lymph node along course of deep brachial artery
  20. Biceps brachii muscle (short head)
  21. Biceps brachii muscle (long head)
  22. Branches of musculocutaneous nerve (to biceps brachii muscle)
  23. Muscular branch radial artery
  24. Radial artery (note anomalous, but not infrequent, high origin from brachial artery)
  25. Brachialis muscle
