Your spine is like a daisy chain. It is made up of a long chain of 26 bones called vertebrae that run down the middle of your back. Without a spine to hold us upright our bodies would slump forwards.
If you view your spine sideways it is like an S-shaped, which makes it springy so it can cope with all the different movements and positions that you do above your legs.
Did you know?Children have 33 vertebrae. As you grow, some of the vertebrae at the bottom of your spine will join together reducing the number to 26.
