Notochord

Real World Example

Imagine trying to set up a tent, but the main pole is missing, making it difficult to give the tent its shape and stability. The notochord in chordates is similar to that missing pole; it's a flexible, rod-like structure that provides essential support and structure to the body. Just as the tent pole helps the tent stand upright and maintain its shape, the notochord helps a chordate's body maintain its form and flexibility, ensuring everything is held together properly.
