Final answer:
The pressure changes caused by the stapes set the cochlear partition into a vibr atory motion and the tectorial membrane to move back and forth
Step-by-step explanation:
.When the stapes bone in the middle ear presses against the oval window, it creates pressure changes that set the cochlear partition into a vibr atory motion. This motion is transferred to the fluid-filled cochlea, which contains the auditory receptors responsible for hearing.
Additionally, the movement of the cochlear partition causes the tectorial membrane, a gel-like structure within the cochlea, to move back and forth. This movement is crucial for the stimulation of hair cells and the generation of elec
