Functions of the cochlea in the inner ear.

In the cochlea (cochlear duct) is the organ of Corti – a horizontal membrane that divides the cavity of the cochlear duct into upper and lower halves. Hair cells of different lengths hang down from it, converting the sound wave into nerve impulses. Nerves depart from the hair cells, connecting to the auditory nerve, which goes to the temporal lobe of the cerebral cortex, where impulses are recognized. In general, thanks to the receptors in the cochlea, we hear.
