====== Axillary nerve ====== The axillary nerve or the [[circumflex nerve]] is a [[nerve]], that originates from the [[brachial plexus]] (upper trunk, posterior division, posterior cord) at the level of the [[axilla]] (armpit) and carries nerve fibers from [[C5]] and [[C6]]. The axillary nerve travels through the quadrangular space with the posterior circumflex [[humeral artery]] and vein. Yoon JS, Park JH, Levin J, Roh EY, Park HJ, Won SJ.
