ILEUM/ILIUM
This is another silly mistake, but taken as major error. We often get confused between ileum and ilium, iliac artery is often times mistakenly written as ileac artery, and so on. There is a very simple way to remember Iliac and Ileum and not get confused between the two.
ILEUM: The third and longest portion of the small intestine. "E" corresponds to Eat, Enteral or Endoscopy, meaning intestines. So, for any intestines related things doctor dictates, it will be ileum.
Iliac Artery: It will always be iliac artery, and not ileac artery.
BOTTOM LINE
Ileum: "E" stands for Eating, Endoscopy.
