The contents of the axilla region include muscles, nerves, vessels, and lymphatics: Axillary artery (and branches) - the main artery supplying the upper limb.It is commonly referred as having three parts; one medial to the pectoralis minor, one posterior to pectoralis minor, and one lateral to pectoralis minor. The axillary artery, which is a continuation of the subclavian artery is divided into three parts by the pectoralis minor muscle. If the axillary artery is ligated distal to the humeral and subscapular branches, the blood flow in the limb is re-established through an anastomosis between these branches and the profunda brachii. Former branch coursed superficial to median nerve in arm and continued in the forearm as such while later one after giving branches of brachial artery in the arm continued as ulnar artery in forearm and . 3 Parts of Axillary Artery: In relation to Pectoralis Minor muscle. Conditions associated with axillary nerve dysfunction include fracture of the humerus (upper arm bone), pressure from casts or splints, and improper use of crutches.
