Think back to last Halloween for a minute. Chances are, the month before, your friends were busily planning their costumes, there were sales on big bags of candy, and decorations started popping up everywhere. Wherever you looked, there were vampires, ghosts, or bony skeletons grinning back at you.
And although vampires and ghosts don't really exist, you can bet that skeletons do! Every single person - and every other mammal - has a skeleton made up of hundreds of bones. These bones provide structure to your whole body, allow you to move in many ways, protect your internal organs, and more. It's time to get busy and look at all your bones - the adult human body has 206 of them!
What Are Bones Made Of?
If you've ever seen a real skeleton or fossil in a museum, you might think that all bones are dead. And although bones in museums are dry, hard, brittle, or crumbly, the bones in your body are very different. The bones that make up your skeleton are all very much alive, growing and changing all the time like other parts of your body.
