Why is the spine highly flexible?

The spine is like a bendy ladder that lets you twist and turn easily.

Your spine has many small parts called vertebrae, kind of like the rungs on a ladder. Each one can move just a little, so when you bend or turn your body, they all work together smoothly, like how each rung of a ladder moves just a little to help the whole ladder bend.

Being flexible helps you do fun things, like crawling into a small space, playing tag, or even riding a bike. If your spine were stiff like a ruler, it would be hard to move around, and you’d probably feel sore after jumping on the trampoline!

So, your spine is highly flexible because it has many little parts that can all move together, helping you twist, bend, and play like a happy kid.
