Pectoral region and axilla
Left axilla (continued); brachial plexus and axillary artery
The axillary vein and its branches have been cut away. Component parts of the brachial plexus have been separated slightly.
1 . Internal jugular vein
2 . Anterior scalene muscle
3 . Jugular trunk
4 . Subclavian artery
5 . Phrenic nerve
6 . Subclavian vein (cut off)
7 . Subscapularis muscle
8 . Rib II
9 . Long thoracic nerve
10 . Serratus anterior muscle
11 . Upper pointer: Cervical nerve V Lower pointer: Cervical nerve VI
12 . Cervical nerve VII
13 . Cervical nerve VIII
14 . Suprascapular nerve
15 . Transverse scapular artery
16 . Lateral cord of brachial plexus
17 . Branch axillary artery (to subscapularis muscle)
18 . Coracoid process of scapula
19 . Axillary nerve
20 . Musculocutaneous nerve
21 . Upper pointer: Coracobrachialis muscle Lower pointer: Anterior circumflex artery of humerus
22 . Posterior circumflex artery of humerus
23 . Axillary artery (note anomalous bifurcation a short distance distal to pointer. The lateral branch continues as the radial artery, the medial branch as the brachial artery)
24 . Radial nerve
25 . Thoracodorsal nerve
26 . Median nerve
27 . Biceps brachii muscle
28 . Ulnar nerve
29 . Middle antibrachial cutaneous nerve
30 . Thoracodorsal artery
