General Information
Term octopaminergic VUMd neuron ID (Ontology) FBbt:00110160 (Fly Anatomy)
Definition Octopaminergic neuron of the VUM cluster, whose cell body is located more posteriorly than those of OA-VUMa neurons, in the labial segment. Its primary neurite projects dorsally through the median tracts. In the area ventral to the esophagus foramen, the neurite branches and forms a pair of secondary neurites that descend through the cervical connective and innervate the ventral nerve cord. Similarly to OA-VUM neurons, VUMd neurons form spiny dendritic arborizations in the posterior slope 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-VUMd"
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).
