General Information
Term larval abdominal 1 transverse nerve ID (Ontology) FBbt:00052540 (Fly Anatomy)
Definition Larval transverse nerve found in abdominal segment 1. A parasympathetic organ is found at its base and it bifurcates relatively close to its exit point from the ventral nerve cord (Santos et al., 2006). Since there is no VT1 muscle in this segment (Campos-Ortega and Hartenstein, 1997), this nerve does not carry a VT1 motor neuron, unlike transverse nerves in other segments.[ FlyBase:FBrf0089570 FlyBase:FBrf0195119 ]
Also Known As "larval A1 transverse nerve"
Comment Gorczyca et al. (1994) - FBrf0075005 claim that this does not exist, despite what appears to be an A1 nerve in their figure 2A.
