Question

The vibrations from the ear drum are transmitted through ear ossicles to

• A. Auditory nerves
• B. Cochlea
• C. Oval window
• D. Tectorial membrane

Answer 1

The Correct Option is C

• The ear drum (tympanic membrane) receives sound vibrations and passes them to the ossicles (the small bones in the middle ear). The ossicles then transmit these vibrations to the oval window, a membrane-covered opening that leads to the inner ear (cochlea).
• The oval window is the correct point where the vibrations from the ossicles are transmitted into the cochlea, which then transduces the vibrations into electrical signals for the auditory nerves.

The correct answer is (C) : Oval window.

Answer 2

The correct answer is: (C) Oval window.

The ear drum (tympanic membrane) vibrates when sound waves hit it. These vibrations are then transmitted through three small bones in the middle ear called the ear ossicles. The ear ossicles include the malleus (hammer), incus (anvil), and stapes (stirrup). They amplify and transfer the vibrations to the next structure in the ear.

The final ossicle, the stapes, is connected to the oval window, which is a membrane-covered opening to the inner ear. When the stapes vibrates against the oval window, it creates pressure waves in the fluid-filled cochlea of the inner ear, initiating the process of hearing.

Thus, the vibrations from the ear drum are transmitted through the ear ossicles to the oval window.
