What does the cochlear nerve do?

The cochlear nerve is primarily responsible for transmitting the electrical impulses generated for hearing and localization of sound. The nerve has its origin in the bipolar cells of the spiral ganglion of the cochlea, which is located adjacent to the inner margin of the bony spiral lamina.

What is the main function of CN VIII?

This cranial nerve has a vestibular part, which functions in balance, equilibrium, and orientation in three-dimensional space, and a cochlear part, which functions in hearing.

What does the vestibulocochlear nerve control?

The vestibulocochlear nerve (8th cranial nerve) is a sensory nerve. It is made up of two nerves, the cochlear, which transmits sound and the vestibular which controls balance.

What exactly does the vestibular system detect?

Overview. The vestibular system provides the sense of balance and the information about body position that allows rapid compensatory movements in response to both self-induced and externally generated forces.

What are the parts of the vestibulocochlear nerve?

People who ask “What is the vestibulocochlear nerve?” should know about the components that make up this nerve. In fact, the vestibulocochlear nerve is composed of two major parts. These would be the vestibular fibers and the cochlear fibers. Basically, vestibular and cochlear parts of this nerve have different functions.

Is the vestibulo ocular reflex a gaze stabilizing reflex?

The vestibulo-ocular reflex (VOR) is a gaze stabilizing reflex: the sensory signals encoding head movements are transformed into motor commands that generate compensatory eye movements in the opposite direction of the head movement, thus ensuring stable vision. From: Development of Auditory and Vestibular Systems, 2014.

How does the vestibulo ocular reflex work in monkeys?

In particular, primates like humans and monkeys make eye-head gaze shifts which combine saccadic eye movements and head movements to redirect their fovea to a new visual target of interest. They also make eye-head gaze pursuit movements to track slowly moving visual targets with their fovea.

Where does the cochlear root meet the vestibular ganglion?

The cochlear root penetrates the anterior lower quadrant of the fundus of the internal acoustic meatus and through the longitudinal canals of the modiolus, it reaches the spiral canal of the modiolus in which the spiral ganglion is placed. The vestibular root connects to the vestibular ganglion, and it lies at the fundus of the internal meatus.
