  VI. The Arteries. 4b. The Axilla. Gray, Henry. 1918. Anatomy of the Human Body.
The axillary artery and vein, with the brachial plexus of nerves, extend obliquely along the lateral boundary of the axilla, from its apex to its base, and are placed much nearer to the anterior than to the posterior wall, the vein lying to the thoracic side of the artery and partially concealing it.
At the forepart of the axilla, in contact with the Pectorales, are the thoracic branches of the axillary artery, and along the lower margin of the Pectoralis minor the lateral thoracic artery extends to the side of the chest.
artery and the descending branch of the transverse cervical; the other is continued along the axillary border of the scapula, between the Teres major and minor, and at the dorsal surface of the inferior angle anastomoses with the descending branch of the transverse cervical.

When the location of the artery and the plexus is not immediately apparent, asking the patient to adduct the arm against resistance during palpation of the artery tenses the pectoralis and coracobrachialis muscles.
However, when the axillary artery is punctured before the plexus is stimulated (rare), we do not continue searching for stimulation but resort to the transarterial technique and inject one third of the total volume of the local anesthetic posterior and one third anterior to the axillary artery.
The musculocutaneous nerve is not consistently blocked with the axillary brachial plexus block, because this nerve leaves the brachial plexus sheath proximally.

 Axillary artery - Wikipedia, the free encyclopedia
In human anatomy, the axillary artery is a large blood vessel that conveys oxygenated blood to the lateral aspect of the thorax, the axilla (armpit) and the upper limb.
The axillary artery is often referred to as having three parts, with these divisions based on its location relative to the pectoralis minor muscle, which is in front of the artery.
The axillary artery is accompanied by the axillary vein along its length.

 Axillary nerve - Wikipedia, the free encyclopedia
The axillary nerve is a nerve of the human body, that comes off the posterior cord of the brachial plexus at the level of the axilla (armpit) and carriers nerve fibers from C5 and C6.
The axillary nerve also carries sensory information from the shoulder joint, as well as the skin covering the inferior region of the deltoid muscle (which is innervated by the Superior Lateral Cutaneous Nerve branch of the Axillary nerve).
