The muscles have been retracted to show the course of the musculocutaneous nerve.
- Radial nerve
- Vertebral margin of scapula
- Teres major muscle
- Thoracodorsal artery
- Latissimus dorsi muscle (tendon of insertion)
- Triceps brachii muscle
- Superior ulnar collateral artery
- Ulnar nerve
- Medial intermuscular septum
- Median nerve
- Brachial artery
- Joint of humerus
- Middle cord of brachial plexus
- Upper pointer: Musculocutaneous nerve Lower pointer: Branches of musculocutaneous nerve (to coracobrachialis muscle)
- Lateral head of median nerve
- Posterior circumflex artery of humerus
- Coracobrachialis muscle
- Medial head of median nerve
- Lymph node along course of deep brachial artery
- Biceps brachii muscle (short head)
- Biceps brachii muscle (long head)
- Branches of musculocutaneous nerve (to biceps brachii muscle)
- Muscular branch radial artery
- Radial artery (note anomalous, but not infrequent, high origin from brachial artery)
