Utricular nerve

Nervus utricularis

Definition

Utricular nerve is a neuronal branch which transmits sensory information from the (macula of the) utricle, which is part of the membranous labyrinth. These neural afferents run in the superior branch of vestibular nerve, along with sensory neurons from other components of membranous labyrinth, including the (ampullas of) lateral and anterior semicircular canals and superior part of the (macula of the) saccule.

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