Auricular branch of vagus nerve
|Nerve: Alderman's nerve|
|Plan of upper portions of glossopharyngeal, vagus, and accessory nerves. (Auricular labeled at top center.)|
|Latin||ramus auricularis nervi vagi|
|Gray's||subject #205 911|
It arises from the jugular ganglion, and is joined soon after its origin by a filament from the petrous ganglion of the glossopharyngeal; it passes behind the internal jugular vein, and enters the mastoid canaliculus on the lateral wall of the jugular fossa.
The nerve reaches the surface by passing through the tympanomastoid fissure between the mastoid process and the tympanic part of the temporal bone, and divides into two branches:
- one joins the posterior auricular nerve.
- the other is distributed to the skin of the back of the auricula and to the posterior part of the external acoustic meatus.
This nerve may be involved by the glomus jugulare tumour.
