Front

What is the function of the Ear Drum?

Back

The Ear Drum, or tympanic membrane, vibrates in response to sound waves, transmitting sound to the ossicles.

Front

What is the Oval Window?

Back

The Oval Window is a membrane-covered opening that leads from the middle ear to the inner ear, transmitting sound vibrations to the cochlea.

Front

What is the Auricle?

Back

The Auricle, or pinna, is the visible part of the ear that helps to collect sound waves and direct them into the ear canal.

Front

What is the role of the Eustachian Tube?

Back

The Eustachian Tube equalizes pressure between the middle ear and the outer ear, allowing for proper hearing.

Front

What are the three bones in the middle ear?

Back

The three bones are the Malleus (hammer), Incus (anvil), and Stapes (stirrup), which amplify sound vibrations.

Front

What is the Cochlea?

Back

The Cochlea is a spiral-shaped organ in the inner ear that contains sensory receptors for hearing.

Front

What is the function of the Stapes?

Back

The Stapes transmits sound vibrations from the incus to the oval window of the cochlea.

Front

What is the Vestibule?

Back

The Vestibule is a part of the inner ear that helps with balance and spatial orientation.

Front

What is the role of the Incus?

Back

The Incus is one of the three ossicles that transmit sound vibrations from the malleus to the stapes.

Front

What is Perilymph?

Back

Perilymph is the fluid that fills the space between the bony labyrinth and the membranous labyrinth in the inner ear.
