General Information
Term larval abdominal CCAP neuron ID (Ontology) FBbt:00111331 (Fly Anatomy)
Definition Larval neuron that expresses CCAP (Crustacean cardioactive peptide) (FBgn0039007) and whose soma is located around the abdominal neuromeres. There are two neurons in each hemineuromere, except in A8 and A9 where there are 3. It sends a neurite beneath the transversal projection TP4 ventromedially, where the neurites from both sides join in proximity to the VM fascicle. These neurites from extensive arborizations along the midline between the DM and VM fascicles.[ FlyBase:FBrf0194317 FlyBase:FBrf0201188 FlyBase:FBrf0204350 ]
Comment According to Park et al. (2008) - FBrf0210278, some of these express AstB, but not clear which. Vomel and Wegener (2008) say 'VL1' neurons express CCAP and Mip (AstB), but say they are in t3-a4 and a6-a7.
