Anatomical terms of neuroanatomy[edit on Wikidata]

The vagal trigone (ala cinerea) is a triangular eminence upon the rhomboid fossa produced by the underlying dorsal nucleus of vagus nerve.

The vagal trigone is separated from the area postrema by a narrow strip of thickened ependyma – the funiculus separans.
