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
