The lateral root of median nerve is a source of the median nerve, originating off the lateral cord of the brachial plexus.{{cite web |title=Lateral Root of Median Nerve |url=https://www.elsevier.com/resources/anatomy/nervous-system/peripheral-nervous-system/lateral-root-of-median-nerve-left/21378#section-origin-1 |website=Elsevier Complete Anatomy |access-date=27 November 2024 |language=en-us}} It is typically one of two nerve roots forming the median nerve, the other being the medial root, although anatomical variations in which the median nerve instead has three or four nerve roots have been described in medical literature.{{cite journal |last1=Samarawickrama |first1=M.
