General Information
Term larval ventral multidendritic neuron vdaB ID (Ontology) FBbt:00002056 (Fly Anatomy)
Definition Larval class IV multidendritic neuron with its soma in the ventral vdaA-D cluster, usually posterior to vdaA and anterior to vdaC and vdaD (Grueber et al., 2003; Orgogozo and Grueber, 2005; Veling et al., 2019). Its dendrites cover a ventral region of the body wall of its segment and do not overlap with the dendrites of the anterior ventral (vdaa) neuron (Grueber et al., 2002). Its axon fasciculates with the segmental nerve (Campos-Ortega and Hartenstein, 1997). Its axon terminals are found in a ventral region of the nociceptive neuropil (Li et al., 2019).[ FlyBase:FBrf0089570 FlyBase:FBrf0148966 FlyBase:FBrf0157166 FlyBase:FBrf0183734 FlyBase:FBrf0244192 FlyBase:FBrf0244259 ]
Also Known As"larval C4da V neuron" ; "larval class IV dendritic arborization ventral neuron" ; "vmd1a"
