Fluid filled tube, hair cells stretch between the membranes, vibrates and generates an action potential which travels along the audatory nerve to the brain
2 of 6
Cochlea implant
Picked up by microphone, pricessed into an electrical impulse, signals are radiowave, travel down wire electrodes, when recieved a electric current stimulates the audatory nerve
