Did you know that all vertebrates start with a notochord?

Really? I had no idea what that was!

Yeah, it's like a primitive backbone that helps in development.

That's fascinating! I love learning about biology.

Root Explanation

Notochord → It is formed from "noton" (Greek, meaning back) and "chordē" (Greek, meaning string). The word "notochord" refers to a flexible rod-like structure found in the embryos of all chordates, which serves as a primitive backbone.

Memory Tip

Think of the 'back' ('noton') and a 'string' ('chordē') that supports the body — that's what a notochord does, acting like a primitive backbone.
