Posterior ampullary nerve

Nervus ampullaris posterior

  • Synonym: Singular nerve

Definition

Posterior ampullary nerve is a neuronal branch which transmits sensory information from the ampulla of posterior semicircular canal, which is part of the membranous labyrinth. These neural afferents run in the inferior branch of vestibular nerve, along with sensory neurons from the inferior part of the macula of saccule.

All neurons in the inferior branch of vestibular nerve end up in the inferior division of vestibular ganglion.
