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”!


Dr. Dyche was born in New Jersey and trained at Penn State’s Hershey Medical Center before coming to Des Moines in 1976. Over 30 plus years he has taught gross anatomy, embryology and neuroanatomy. He also served in administration as associate dean for basic sciences, dean of the College of Health Sciences, and acting director of the PA program. He was one of the founding instructors of CPR and ACLS at a time when few medical schools offered this training. He retired to Oregon in 2008, then returned to DMU in 2009. Did he miss the tornadoes, the below zero wind chills or the cadavers?
