When hair cells within the cochlea are stimulated by sound wave vibrations, they stimulate nearby sensory neurons of the spiral ganglion. The signals then get sent to the cochlear nerve and then to the vestibulocholear nerve (CN VII). These signals then get sent to the cochlear nucleus of the medulla oblongata which then get relayed to the inferior colliculus of the midbrain. These signals then get sent to the thalmus where they are relayed to the auditory cortex where specific areas process the pitch and frequency of the sound. The reflexatory response to sound is directed by the inferior colliculus (ie turn head toward sound) Actually, there are two errors in your answer. First: it is vestibulocochlear Second: it is cranial nerve VIII
Nerves in the ear respond to the mechanical stress of soundwaves and transmit the stress/sound accoundingly (super simplified answer)
Encoding
sound waves enter the ear canal and cause the eardrum to vibrate.VIBRATIONS pass through 3 connected bones in the middle earThis motion SETS FLUID MOVING in the inner ear.Moving fluid bends thousands of delicate hair-like cells which convert the vibrations into NERVE IMPULSES.Nerve impulses are CARRIED to the brain by the auditory nerveIn the brain, these impulses are CONVERTED into what we "hear" as sound.
The Optic Nerve AKA Cranial Nerve II from eye to brain for sight and Craniel Nerves III (Oculomotor) and IV (Trochlear) for Eye movement.
The cerebrum controls all senses, memory, and the ability to learn. :) *Sound is processed in the auditory cortex according to my understanding. 2-9-11 HMS
No. The 'message' is carried by the auditory nerve to the brain.
The auditory nerve carries auditory impulses to the brain.
The Auditory Nerve does this.
the cochlear nerve
The Auditory Cortex
The auditory nerve is responsible for relaying vibrations from the cochlea, in the inner ear, to the brain as electrical impulses. The auditory centre of the brain then interprets these as sound.

Nerves in the ear respond to the mechanical stress of soundwaves and transmit the stress/sound accoundingly (super simplified answer)
The auditory canal to the eardrum then the auditory nerve sends it to the brain for interpretation.
No, electrical impulses generated within the auditory senses do that.
Primary auditory cortex
In the inner ear, "sound" is translated into electrical energy. This electrical energy is transmitted to the brain via the 8th cranial nerve more commonly called the auditory, acoustic or vestibulocochlear nerve. The brain receives the information and translates it into what we "hear", or at least into what is most important for us to hear at that time.
