General Information
Term octopaminergic VUMa neuron ID (Ontology) FBbt:00110155 (Fly Anatomy)
Definition Octopaminergic neuron of the VUM cluster, whose cell body is located more anteriorly than those of OA-VUMd neurons, in either the mandibular or maxillary segments. Its primary neurite projects dorsally through the median tracts. It bifurcates in the area ventral to the esophagus foramen and form spiny dendritic arborizations in the posterior slope. Pairs of secondary processes emerge from these arbors and project to distinct brain regions, forming varicose nerve terminals (Busch et al., 2009, Busch and Tanimoto, 2010).[ FlyBase:FBrf0207458 FlyBase:FBrf0210649 ]
Also Known As "OA-VUMa" ; "ventral unpaired median octopaminergic anterior neuron"
Comment The neurotransmitter was assessed by immunostaining with an anti-octopamine (OA) antibody in cells labelled with tdc2-GAL4 (FBti0101786) and NP7088-GAL4 (FBti0037217) (Busch et al., 2009) or only using the tdc2-GAL4 (FBti0101786) (Busch and Tanimoto, 2010).
