General Information

Term

adult octopaminergic subesophageal VUM neuron

ID (Ontology)

FBbt:00110154 (Fly Anatomy)

Definition

An unpaired octopaminergic neuron of the VM cluster whose cell body is located on the midline of the gnathal ganglion of the adult brain. The primary neurites of OA-VUM neurons join one of the three median tracts along the anterioposterior axis and mainly innervate the periesophageal region. These neurites follow the tracts toward the posterior ventral area of the esophagus foramen where they symmetrically branch out to innervate the cerebral ganglion and subesophageal zone and in some cases the ventral nerve cord. Two main subtypes can be identified: OA-VUMa and OA-VUMd (Busch et al., 2009; Certel et al., 2010).[ FlyBase:FBrf0191080 FlyBase:FBrf0207458 FlyBase:FBrf0212145 ]

Also Known As

"adult subesophageal ventral unpaired median octopaminergic neuron" ; "OA-VUM" ; "subesophageal ganglion ventral unpaired median 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) (Certel et al., 2010).
