The auditory nerve is the 8th cranial nerve, and pathology of the 8th canial nerve has already been stated by me as a primary cause of sensorineural deafness. In an individual with normal hearing, the 8th cranial nerve extends from the inner ear to the brain stem. Sound stimuli is picked up in the 8th cranial nerve, which then transmits it to the brainstem, where the brainstem then sends the stimuli to the auditory processing center in the brain where it is processed to meaning.
In pathology of the 8th cranial nerve, leading to sensorineural deafness, the
8th cranial nerve is damaged, and therefore, is unable to transmit sound stimuli to the brainstem. Because the nerve itself has not transmitted the sound stimuli to the brainstem, it is never reached in the auditory processing center. However, that is not a neurological problem. It is the pathology of the nerve that is responsible for the lack of sound stimuli being received in the brain. As the 8th cranial nerve has long been identified as a causative agent in sensorineural deafness, everything I have said is supported, whether the damage to the nerve is where it attaches to the inner ear, or whether the problem with the nerve is where it attaches to the brain stem. It is still the 8th cranial nerve that is responsible.:roll:
Yes, the auditory nerve is the 8th carnial nerve, but where your statements go wrong is that you ignore the fact that connections at the brain stem its self is not in the inner ear its self. You blatantly ignore the fact that damage at or to that connection, regardless of the cause, can still result in SN hearing loss.
