Which cranial nerve is responsible for equilibrium?
vestibulocochlear nerveThe vestibulocochlear nerve is responsible for the sense of hearing and balance (body position sense).
Which of the following cranial nerves carries equilibrium messages?
Vestibulocochlear nerve (VIII): A sensory nerve that carries impulses for hearing and equilibrium from the ear to the brain. Glossopharyngeal nerve (IX): A mixed nerve. The sensory fibers of this nerve carry basic sensory information and taste sensations from the pharynx and tongue to the brain.
What do the 7th and 8th cranial nerves do?
The 8th nerve, also known as the vestibulocochlear nerve, mainly transmits information from the hearing organ (cochlea) and the vestiular organ to the brain. The 8th nerve traverses the internal auditory canal, which also contains the 7th nerve, the nervous intermedius, and the labyrinthine artery.
