What the skeleton does
Bones do more than hold the body up. They protect organs such as the brain and heart, anchor the muscles that move you, store minerals including calcium, and, inside some bones, red bone marrow makes blood cells.
Why the small bones are easy to forget
Most people remember the femur, the skull and the ribs. The tiny ones, like the stapes in the middle ear, are often missed, and the hyoid in the neck surprises many people because it is the only bone that does not join to another one. Taking the quiz with a child or a student and reading each explanation out loud is a good way to make the facts stick.
