Vestibulocochlear
The vestibulocochlear nerve, also known as cranial nerve VIII, is a purely sensory nerve that carries information related to hearing and balance. It consists of two functionally independent divisions: the cochlear nerve, which transmits auditory information from the cochlea to the brain, and the vestibular nerve, which conveys information about head position and movement from the vestibular apparatus.
Anatomy and connections: The cell bodies for the cochlear fibers reside in the spiral ganglion, while the
Pathways and functions: Auditory information proceeds from the cochlear nuclei through central auditory pathways to the
Clinical relevance: Lesions can cause sensorineural hearing loss, vertigo, and imbalance on the affected side. Vestibular
