What is the description of vestibulocochlear nerve?
The vestibulocochlear nerve or auditory vestibular nerve, also known as the eighth cranial nerve, cranial nerve VIII, or simply CN VIII, is a cranial nerve that transmits sound and equilibrium (balance) information from the inner ear to the brain.

What is vestibulocochlear nerve also called?
The vestibulocochlear nerve, also known as cranial nerve eight (CN VIII), consists of the vestibular and cochlear nerves. Each nerve has distinct nuclei within the brainstem.
Is vestibulocochlear nerve motor or sensory?
Special Sensory
| Nerves in Order | Modality |
|---|---|
| Vestibulocochlear | Special Sensory |
| Glossopharyngeal | Branchial Motor Visceral Motor Visceral Sensory General Sensory Special Sensory |
| Vagus | Branchial Motor Visceral Motor Visceral Sensory Special Sensory |
| Spinal Accessory | Branchial Motor |
Which sensations does the vestibulocochlear nerve carry?
Introduction. The vestibulocochlear nerve is the eighth cranial nerve. Its cochlear branch is responsible for the special sensation of hearing, and its vestibular portions are involved in balance, spatial sensation, and posture.
How do you remember the cranial nerves Mnemonic?
Cranial nerve mnemonics to remember the names of the nerves in order include: On old Olympus’s towering top, a Finn and German viewed some hops. Ooh, ooh, ooh to touch and feel very good velvet.
Where do the Vestibulocochlear nerve fibers for hearing terminate?
The nerve fibers (about 40 000 of them) cross the foramina in the tractus spiralis foraminosus and end at the cochlear ganglion.
What is the function of the glossopharyngeal nerve?
The glossopharyngeal nerve is the ninth set of 12 cranial nerves (CN IX). It provides motor, parasympathetic and sensory information to your mouth and throat. Among its many functions, the nerve helps raise part of your throat, enabling swallowing.
Is the vestibulocochlear nerve the auditory nerve?
The vestibulocochlear nerve is located in the internal auditory meatus (internal auditory canal). The nerve is responsible for equilibrium and hearing.
What are the two branches of the vestibulocochlear nerve?
At the fundus of the internal acoustic meatus, the nerve splits into its two roots, vestibular and cochlear.
What is the origin of the vestibulocochlear nerve?
The vestibulocochlear nerve originates between the pons and the medulla oblongata, by two roots, vestibular and cochlear, emerging behind the facial nerve (VII) and in front of the inferior cerebellar peduncle.
What are the 12 cranial nerves mnemonic?
Remembering cranial nerve names in order of CN I to CN XII:
- On old Olympus’s towering top a Finn and German viewed some hops.
- Ooh, ooh, ooh to touch and feel very good velvet. Such heaven!
Where does the vestibulocochlear nerve originate?
Where do the vestibulocochlear nerve fibers for hearing terminate?
What nerve controls the gag reflex?
The afferent limb of the reflex is supplied by the glossopharyngeal nerve (cranial nerve IX), which inputs to the nucleus solitarius and the spinal trigeminal nucleus. The efferent limb is supplied by the vagus nerve (cranial nerve X) from the nucleus ambiguus. All of these are located in the medulla.
What is the function of the vestibule and the semicircular canals?
The vestibule contains two quite separate systems for gathering information on head postion. One system, the semicircular canals, detects movement of the head in any direction, while the other system, the saccule and utricle system, can register the position of the head when it is not moving.
Where is vestibulocochlear nerve located?
internal auditory meatus
The vestibulocochlear nerve is located in the internal auditory meatus (internal auditory canal). The nerve is responsible for equilibrium and hearing. Conditions of the vestibulocochlear nerve include vestibular neuritis, labyrinthitis, and acoustic neuroma.
