Question

The bone that is attached to the eardrum is called the ________; the bone that is connected to the oval window is called the ________.

Answer 1

Answer:

The bone that is attached to the eardrum is called the hammer; the bone that is connected to the oval window is called the stirrup.

Explanation:

The vibrations are transmitted to the interior of the ear through the three bones located in the middle ear: hammer, anvil and stirrup. These three bones form a kind of bridge, the hammer is a bone that is connected to the tympanic membrane or eardrum and is responsible for transmitting the sound waves that arrive through the air to the inner ear. The vibrations first reach the anvil through the joint incudomalear and then to the stirrup (stapes), which is the last bone where the sound arrives and that is connected to the oval window (membrane that covers the entrance to the cochlea in the inner ear, when the sound waves are transmitted from the eardrum to the oval window, the middle ear functions as an acoustic transformer).
