The axillary artery is found deep to the pectoralis minor. It has three segments and gives off a number of branches:

Segment	Artery	Target
1	Superior thoracic	Intercostal spaces 1 and 2
2	Thoraco-acromial	Deltoid Acromion Clavicle Pectoralis
2	Lateral thoracic	Chest wall
3	Posterior circumflex humeral	Deltoid Shoulder joint
	Anterior circumflex humeral	Anterior aspect of shoulder joint
	Subscapular	Latissimus dorsi (via the thoracodorsal) Scapular anastomosis (via the circumflex scapular)

Branches of the brachial plexus
Origin	Nerve	Target
C5	Phrenic	Diaphram
C5	Dorsal scapular	Rhomboids
Upper trunk	Nerve to subclavius	Subclavius
Lateral cord	Lateral pectoral	Pectoralis major
Posterior cord	Upper subscapular	Subscapularis
	Thoracodorsal	Longissimus dorsi
	Lower subscapular	Subscapularis, teres major
Medial cord	Medial pectoral	Pectoralis major
	Medial brachial cutaneous	-
