Shoulder
Capsule and ligaments of left shoulder joint, anterior view
The subscapular muscle has been partially cut away from the specimen shown previously (91-7). The capsule of the shoulder joint is reinforced anteriorly by the middle and inferior glenohumeral ligaments (5,6). The contours of these extracapsular ligaments are not clearly visible externally. They are more evident in the interior of the joint (94-7).
  1. Superior transverse ligament of scapula
  2. Scapular notch
  3. Subscapularis muscle
  4. Subscapular fossa
  5. Joint capsule of humerus (pointer indicates position of middle glenohumeral ligament, visible internally in view 94-7)
  6. Joint capsule of humerus (pointer indicates position of inferior glenohumeral ligament, visible internally in view 94-7)
  7. Triceps brachii muscle (long head)
  8. Circumflex scapular artery
  9. Suprascapular nerve
  10. Transverse scapular artery
  11. Coracoclavicular ligament (cut off)
  12. Coracoid process of scapula
  13. Pectoralis minor muscle (tendon of insertion)
  14. Acromial articular surface
  15. Bursa of subscapularis muscle (translucent area of wall indicates position of a deeper bursal sac both bursae communicate with cavity of shoulder joint)
  16. Coracobrachialis muscle and short head bicipitis brachii muscle
  17. Coracoacromial ligament
  18. Coracohumeral ligament
  19. Tendon of subscapularis muscle (lower portion muscular)
  20. Biceps brachii muscle (long head, elevated)
  21. Body of humerus
  22. Anterior circumflex artery of humerus
  23. Pectoralis major muscle
  24. Posterior circumflex artery of humerus
  25. Teres major muscle
  26. Latissimus dorsi muscle
