General Information
Term larval Va Capability neuron ID (Ontology) FBbt:00110116 (Fly Anatomy)
Definition Larval Capability-expressing neurosecretory neuron whose cell body is located ventrally in an abdominal segment (Kean et al., 2002; Santos et al., 2007). Its axon projects dorsomedially, passing below the central intermediate and dorsal median tracts, to reach the midline near transverse projection 3, where it joins the axon of the contralateral Va neuron (Santos et al., 2007). The two axons project dorsally together a short distance before diverging and forming a loop inside the neuropil and dorsal cortex (Santos et al., 2007). The loop closes just before the neurites leave the ventral nerve cord and innervate an abdominal neurohemal organ (Santos et al., 2007). There is one of these neurons in each A2-A4 hemineuromere (Suska et al., 2011; Gabilondo et al., 2018).[ FlyBase:FBrf0146873 FlyBase:FBrf0201188 FlyBase:FBrf0214309 FlyBase:FBrf0238644 ]
Also Known As"ABCA neuron" ; "larval abdominal Capability neuron" ; "larval ventral abdominal Capability neuron" (for all, see Synonyms field below)
