Have you ever heard of the term proctodaeum?

No, I can't say that I have. What is it?

Root Explanation

Proctodaeum is formed from "procto-" (from Greek "proktos", meaning anus) and "daeu" (from Greek "daio", meaning to give or to provide). The term refers to the embryonic structure that gives rise to the anus and the rectum, thus relating to the development of the anal region.

Memory Tip

Think of 'procto-' relating to the 'anus' and 'daeu' meaning 'to provide' — together, they describe the structure that provides the anus.
