The cochlea contains which send(s) messages through the auditory nerve to the areas of the brain that are responsible for interpreting auditory information.

The cochlea contains organ of cortis which send(s) messages through the auditory nerve to the areas of the brain that are responsible for interpreting auditory information. The Organ of cortis contains the hair cells and nerve receptors for hearing. When the hair cells has been stimulated, it will react to specific sound frequencies. However, only certain hair cells will be stimulated based on the pitch of the sound. The signals produced by the hair cells will turn into nerve impulses which will be sent out by the cochlear portion of the auditory nerve into the brain. This auditory nerve will carry the impulses from cochlea into the mid-brain which is the cochlear nucleus. On other brain pathways that end in the auditory cortex of the brain these nerve impulses were carried.
