The vestibulocochlear nerve is accompanied by the labyrinthine artery, which usually branches off from the anterior inferior cerebellar artery at the cerebellopontine angle, and then goes with the 7th nerve through the internal acoustic meatus to the internal ear. The cochlear nerve travels away from the cochlea of the inner ear where it starts ...
The facial canal gives passage to the facial nerve (CN VII) (hence the name). [1] [verification needed] [better source needed] Its proximal opening is at the internal auditory meatus; its distal opening is the stylomastoid foramen. In humans, the canal is approximately 3 cm long, making it the longest bony canal of a nerve in the human body.
The facial nerve continues traveling through the facial canal, eventually exiting the skull at the stylomastoid foramen. A common mnemonic to remember the anterior quadrants of the inner ear is: "seven up, coke down" (seventh nerve superior, cochlear nerve inferior).
Facial nerve paralysis is a common problem that involves the paralysis of ... the latter two symptoms due to damage to vestibulocochlear nerve and the inner ear. ...
The facial nerve, also known as the seventh cranial nerve, cranial nerve VII, or simply CN VII, is a cranial nerve that emerges from the pons of the brainstem, controls the muscles of facial expression, and functions in the conveyance of taste sensations from the anterior two-thirds of the tongue.
The facial nerve exits the cranial cavity through the internal acoustic meatus and enters the facial canal. Within the facial canal, chorda tympani branches off the facial nerve and enters the lateral wall of the tympanic cavity within the middle ear, where it runs across the tympanic membrane (from posterior to anterior) and medial to the neck ...
The inner ear (internal ear, auris interna) is the innermost part of the vertebrate ear. In vertebrates , the inner ear is mainly responsible for sound detection and balance. [ 1 ] In mammals , it consists of the bony labyrinth , a hollow cavity in the temporal bone of the skull with a system of passages comprising two main functional parts: [ 2 ]
This is combination with the retrolabyrinthine and transmastoid approaches, enables visualization of the entire course of the facial nerve and still preserves function of the inner ear. The middle cranial foassa technique is most commonly used for the decompression of the facial nerve in Bell's palsy and longitudinal temporal bone fracture.
