The incus malleus and stapes channel sound from the external pinna to the inner ear where it is decoded by the brain.

The middle ear bones are the smallest bones in the human body and are very delicate. Muscles and ligaments hold this fragile chain of bones in place and allow them to vibrate back and forth with sounds. The first bone in the chain is called the Malleus (hammer), the second is called the Incus (anvil), and the last bone is called the Stapes (stirrup). The sound vibrations cause the Stapes to move back and forth. This motion is thus transferred to the inner ear.

The colloquial names are the hammer, the stirrup and the anvil, but I don't know what doctors call them.
