ax·il·lar·y nerve

[TA]
nerve that arises from the posterior cord of the brachial plexus in the axilla, passes laterally and posteriorly through the quadrangular space with the posterior circumflex humeral artery; muscular branches pass to the teres minor and wind around the surgical neck of the humerus to the deltoid; terminates as the superior lateral brachial cutaneous nerve.

axillary nerve

one of the last two branches of the posterior cord of the brachial plexus before the posterior cord becomes the radial nerve. It divides into a posterior branch and an anterior branch. The posterior branch innervates the teres minor, part of the deltoideus, and part of the skin overlying the deltoideus; the anterior branch innervates the deltoideus. Some fibers of the nerve also supply the capsule of the shoulder joint.
