Pectoral region and axilla
Nerve and blood supply of left pectoralis major muscle
The pectoralis major (9) has been reflected laterally from its clavicular (2) and sternocostal (3) origins. A narrow band of the pectoral fascia (8) which invested the deep surface of the muscle has been retained.
- Sternocleidomastoid muscle
- Clavicular part pectoralis major muscle (cut across)
- Sternocostal part pectoralis major muscle (cut across)
- Upper pointer: Abdominal part pectoralis major muscle (cut across) Lower pointer: Sheath of rectus abdominis muscle
- Supraclavicular nerves
- Axillary vein
- Anterior thoracic nerve (branches of thoracoacromial vessels lie close to nerve)
- Remnant of pectoral fascia
- Pectoralis major muscle (reflected laterally)
- Pectoralis minor muscle
- Rib II
- Body of sternum
- Pectoral fascia (at former position of lateral border of pectoralis major)
- Serratus anterior muscle
- Lateral cutaneous branch of intercostal nerve VI
