Respuesta :
The structure of the mammalian middle ear exists adapted to transform air pressure waves into fluid pressure waves.
What structures adjust air pressure in the middle ear?
The eustachian tube functions as a pressure release valve to modify the middle ear pressure. The increasing positive pressure within the middle ear or negative pressure in the nasopharynx facilitates the discharge of air or secretions from the middle ear via the eustachian tube to the nasopharynx.
It's coiled to suggest a large exterior area for the extension of the sensory cells. Has numerous sensory cells to sense sound vibrations. Has a thin membrane that vibrates better raising the intensity of sound vibrations; It's filled with a liquid to improve the transmission of sound waves in it.
Therefore, the correct answer is option A) air pressure waves to fluid pressure waves.
