WebThe cochlea is a whorled structure, like the shell of a snail, and it contains receptors for transduction of the mechanical wave into an electrical signal (as illustrated in Figure 17.14). Inside the cochlea, the basilar membrane is a mechanical analyzer that runs the length of the cochlea, curling toward the cochlea’s center. WebSections through the cochlea reveal that it is divided into three channels: cochlear duct, scala vestibuli, and scala tympani. The cochlear duct or scala media is a continuation of the membranous labyrinth into the cochlea; it … WebThe 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. crippa lega nord
