Shoulder
Fascial planes anterior to left shoulder joint
A layer of fascia (6)extends laterally from the short head of the biceps across the shoulder joint. This layer blends with a fascia, aponeurotic in character, which continues upward from the insertion of the pectoralis major (18). The tendon of insertion of the subscapular muscle (4) is covered by a combination of the subscapular fascia. This layer has been reflected superiorly (3).
  1. Subdeltoid bursa
  2. Coracoacromial ligament
  3. Lateral portion of subscapular fascia (reflected superiorly)
  4. Tendon of insertion of subscapularis muscle (pointer on lesser tubercle of humerus)
  5. Coracoid process of scapula
  6. Fascial layer continuous with fascia of biceps muscle
  7. Position of intertubercular sulcus
  8. Anterior circumflex artery of humerus
  9. Coracobrachialis muscle
  10. Biceps brachii muscle (short head)
  11. Pectoralis major bursa (pointer on tendon of long head of biceps muscle)
  12. Brachial veins
  13. Subscapularis muscle
  14. Transverse humeral ligament
  15. Deltoid muscle
  16. Axillary nerve
  17. Body of humerus (covered by periosteum)
  18. Pectoralis major muscle (tendon of insertion)
  19. Cephalic vein
