Question
Which three bones move as a result of the tympanic membrane vibrating from sound waves?
Solution
The three bones that move as a result of the tympanic membrane vibrating from sound waves are:
-
Malleus (Hammer): This is the first bone that is attached to the tympanic membrane. When the tympanic membrane vibrates, it moves the malleus.
-
Incus (Anvil): The malleus is connected to the incus. So, when the malleus moves, it causes the incus to move as well.
-
Stapes (Stirrup): The incus is connected to the stapes. Therefore, when the incus moves, it causes the stapes to move. The stapes is the smallest bone in the human body and it is the final bone in this chain. It transfers the vibrations to the oval window, which is the entrance to the inner ear.
