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
