Editing Brachial plexus (section)

==Function==
The brachial plexus provides nerve supply to the skin and muscles of the arms, with two exceptions: the [[trapezius]] muscle (supplied by the [[spinal accessory nerve]]) and an area of skin near the axilla (supplied by the [[intercostobrachial nerve]]). The brachial plexus communicates through the sympathetic trunk via gray rami communicantes that join the plexus roots.

The terminal branches of the brachial plexus (musculocutaneous n., axillary n., radial n., median n., and ulnar n.) all have specific sensory, motor and proprioceptive functions.<ref>{{Cite book|title=Anatomy and Physiology: The Unity of Form and Function|url=https://archive.org/details/anatomyphysiolog00sala_012|url-access=limited|last=Saladin|first=Kenneth|publisher=McGraw-Hill|year=2007|isbn=9789814646437|location=New York, NY|pages=[https://archive.org/details/anatomyphysiolog00sala_012/page/n505 491]}}</ref><ref>{{Cite web|url=http://www.nysora.com/techniques/nerve-stimulator-and-surface-based-ra-techniques/upper-extremitya/3260-axillary-brachial-plexus-block.html|title=Axillary Brachial Plexus Block|date=2013-09-20|website=www.nysora.com|publisher=New York School of Regional Anesthesia|archive-url=https://web.archive.org/web/20170712104919/http://www.nysora.com/techniques/nerve-stimulator-and-surface-based-ra-techniques/upper-extremitya/3260-axillary-brachial-plexus-block.html|archive-date=2017-07-12|url-status=dead}}</ref>
