The nurse is reviewing the function of the cranial nerves (CNS). Which CN is responsible for conducting nerve impulses to the brain for hearing?

A. VIII: Cranial nerve VIII, also known as the vestibulocochlear nerve, is responsible for transmitting auditory information from the cochlea of the inner ear to the brain, allowing for the perception of sound. It also plays a role in balance by carrying information from the vestibular apparatus regarding head position and movement. B. VI: Cranial nerve VI, the abducens nerve, controls the lateral rectus muscle, which is responsible for outward eye movement. It does not have any function related to hearing. C. V: Cranial nerve V, the trigeminal nerve, is primarily responsible for sensation in the face and motor functions such as biting and chewing. It does not conduct nerve impulses related to hearing. D. VII: Cranial nerve VII, the facial nerve, controls muscles of facial expression and carries taste sensations from the anterior two-thirds of the tongue. While it has some minor roles in the auditory system (such as innervating the stapedius muscle), it is not primarily responsible for conducting nerve impulses related to hearing.
