Anatomy word of the month: duodenum

October 1, 2011 —

Duodenum“Twelve each” in Latin. The duodenum is the first section of the small intestine attached to the outlet of the stomach, the pylorus. Early anatomists measured it as approximately twelve fingers’ breadths long. Duodecim is the number 12 in Latin. Take the Latin number, pass it through old French dozaine into modern English, and you have “dozen”!
