Vibration energy in the tympanic membrane is transmitted through the ossicles to the oval window into the cochlea. Pressure vibration ...

Olivocochlear system
The olivocochlear system is a component of the auditory system involved with the descending control of the cochlea. Its nerve fibres, the olivocochlear bundle (OCB), form part of the vestibulocochlear nerve (VIIIth cranial nerve, also known as the auditory-vestibular nerve), and project from the superior olivary complex in the brainstem (pons) to the cochlea.
