Anatomy word of the month: Crista galli

March 4, 2013 —

rooster-cockscombThe “cock’s comb” is a wedge of bone found on the anterior floor inside of the skull in the midline. The meninges (protective membranes surrounding the brain) are anchored anteriorly at this point. The Latin name for the group of animals including chickens and turkeys is galliformes. Those imaginative ancient anatomists thought that the vertical, curved wedge of bone resembled the comb on a rooster’s head.


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?
