Answer:
Structure that connects the middle and inner ear and allows vibrations to pass into the Cochlea is oval window.
Step-by-step explanation:
The oval window is a membranous structure in relation to the stirrup, the ossicle of the middle ear, whose function is to transmit the vibrations it receives to the inner ear, specifically to the cochlea.
Sound coming from outside produces vibrations received by the eardrum, and transmits these vibrations to the hammer, anvil and stirrup, which also makes the oval window vibrate. Vibrations that reach the cochlea mobilize the liquid that is there, which translates vibrations into nervous impulses.
One can say the oval window is the separation between middle and inner ear.
Other options are not correct because:
- The auditory canal is part of the outer ear, and transmits sound from the outside to the eardrum.
- Hearing aid is a device that allows you to hear when hearing acuity has decreased.
- The cochlear nerve transmits sound related information in the form of nerve impulses.
