Answer:
Vibrations of the auditory ossicles are transmitted to the cochlea via the oval window.
Explanation:
The oval window is a membranous structure that communicates the middle ear with the cochlea of the inner ear, is attached to the stirrup and receives its vibrations from it. The sound waves spread through the air and reach the outer ear, into which they penetrate through the ear canal. In doing so, they stimulate the eardrum, which closes the inner end of the duct. By vibrating this membrane, the vibration of a chain of ossicles located in the middle ear is induced. These ossicles transmit their vibration to the oval window.
