Editing Duodenum (section)

==Etymology==
The name ''duodenum'' is [[Medieval Latin]], short for ''intestīnum duodēnum digitōrum'', meaning "intestine of twelve finger-widths (in length)", genitive{{fact|date=February 2025}} of ''duodēnī'', "twelve each", (related to ''duodecim'' "twelve"). Coined by Gerard of Cremona (d. 1187) in his Latin translation of "Canon Avicennae", "اثنا عشر" itself a loan-translation of Greek dodekadaktylon (δωδεκάδάκτυλον), literally "twelve fingers long". The intestine part was so called by the Greek physician [[Herophilus]] (c. 335–280 BCE) for its length, about equal to the breadth of 12 fingers.<ref>{{cite web|title=duodenum - Origin and meaning of duodenum by Online Etymology Dictionary|url=https://www.etymonline.com/word/duodenum|website=www.etymonline.com}}</ref>
