Notochord
Notochord explained in an easy to understand way:
Imagine trying to set up a tent without a central pole; it would collapse and be unable to maintain its shape. The notochord in chordates functions similarly to that central pole by providing structural support and shape to the organism's body. Just as the tent pole is crucial for the tent's stability and form, the notochord is essential for the chordate's body structure, ensuring it remains flexible yet sturdy enough to support other bodily functions.
