General Information
Term embryonic/larval labral nerve ID (Ontology) FBbt:00001966 (Fly Anatomy)
Definition Nerve of the larval head that carries axons from the labral sense organs (dorsal pharyngeal sense organ, dorsopharyngeal organ and pharyngeal chordotonal organ) to the tritocerebrum (Schmidt-Ott et al., 1994; Hartenstein et al., 2018; Kendroud et al., 2018). It joins the hypopharyngeal nerve and the frontal connective to form the pharyngeal nerve (Hartenstein et al., 2018; Kendroud et al., 2018).[ FlyBase:FBrf0075072 FlyBase:FBrf0147119 FlyBase:FBrf0237251 FlyBase:FBrf0237252 ]
