General Information
Term larval Pdf neuron of abdominal neuromere ID (Ontology) FBbt:00100169 (Fly Anatomy)
Definition Pdf-expressing neuron whose cell body is located in a ventral cluster in the eighth larval abdominal neuromere of the ventral ganglion. There are 8 of these per cluster - each projecting though the paired eighth abdominal nerve to the posterior end of the larva (Helfrich-Forster, 1997). They are glutamatergic motor neurons that arborize over the posterior end of the hindgut, with refined branches and abundant bouton structures (Zhang et al., 2014).[ FlyBase:FBrf0093121 FlyBase:FBrf0226857 ]
Also Known As"PDFAb neuron"
