The vestibular nerve is a crucial part of the inner ear system, responsible for transmitting information about balance and spatial orientation to the brain. It is one of the two branches of the vestibulocochlear nerve (cranial nerve VIII), with the other branch dedicated to hearing. The vestibular nerve collects signals from the semicircular canals and otolith organs, which detect head movements and position relative to gravity. This nerve plays a vital role in maintaining balance and coordinating eye movements. When the vestibular nerve is functioning properly, it helps the body respond to changes in position, preventing dizziness and ensuring stability during movement. Disorders affecting the vestibular nerve can lead to balance issues and vertigo.
