Journeys: Ears. Stop 2

Three little bones

Behind the eardrum is a tiny room of air. It is called the middle ear. Put the three tiny bones in there, each on its own shadow!

This is the hammer. Its handle is joined to the eardrum.

This is the anvil. It got its name because it looks like a blacksmith's anvil.

This is the stirrup, like the loop a rider puts a foot in. It is the smallest bone in the body, smaller than a grain of rice!

That's not its shadow. Compare the shapes.

The chain is ready! Touch the eardrum.

The shake runs along the bones and gets stronger. The stirrup pushes on the oval window of the cochlea.
