Editing Axillary nerve (section)

==Function==
The axillary nerve supplies two [[muscle]]s in the arm: [[deltoid muscle|deltoid]] (a muscle of the shoulder) and [[teres minor]] (one of the [[rotator cuff]] muscles). 
 
The axillary nerve also carries sensory information from the [[shoulder joint]]. It also innervates the skin, covering the inferior region of the deltoid muscle, known as the regimental badge area.<ref name=":2">{{Citation|last=Jacob|first=S.|title=Chapter 2 - Upper Limb|date=2008-01-01|url=http://www.sciencedirect.com/science/article/pii/B9780443103735500051|work=Human Anatomy|pages=5–49|editor-last=Jacob|editor-first=S.|publisher=Churchill Livingstone|language=en|doi=10.1016/b978-0-443-10373-5.50005-1|isbn=978-0-443-10373-5|access-date=2021-01-11|url-access=subscription}}</ref> This is innervated by the [[Superior lateral cutaneous nerve of arm|superior lateral cutaneous nerve]] branch of the axillary nerve.

The [[posterior cord]] of the [[brachial plexus]] splits inferiorly to the glenohumeral joint giving rise to the axillary nerve which wraps around the surgical neck of the humerus, and the radial nerve which wraps around the humerus anteriorly and descends along its lateral border.
