Which part of the ear converts vibrations into nerve impulses? cochlea
auditory nerve
outer ear
eardrum

cochlea

Explanation:

The cochlea is filled with a fluid that moves in response to the vibrations from the oval window. As the fluid moves, 25,000 nerve endings are set into motion. These nerve endings transform the vibrations into electrical impulses that then travel along the eighth cranial nerve (auditory nerve) to the brain.
