There are two of these cells. Processes arborize in the dorsomedial neuropil of anterior neuromeres and some neurites reach the posterior part of a5. The efferents project via the intersegmental nerve. aVM8 VFB:FBbt_00047555 fly_anatomy.ontology Vomel and Wegener, 2008 (FBrf0210246) reported that these cells were located in abdominal neuromere 7. For neurotransmitter expression analysis, Vomel and Wegener, 2008 used Tdc2-GAL4 (tyrosine decarboxylase - implies presence of tyramine) and anti-Tbh (tyramine beta-hydroxylase - implies presence of octopamine). Selcho et al., 2012 used Tdc2-GAL4, validated with anti-Tbh, anti-p-tyramine and anti-conjugated octopamine, to visualize tyraminergic and octopaminergic neurons. These may be motor neurons and may innervate the female reproductive tract (Vomel and Wegener, 2008), but muscle targets have not been demonstrated. larval efferent neuron cell body rind of larval abdominal 8 neuromere larval octopaminergic neuron larval tyraminergic neuron larval abdominal 5 neuromere larval abdominal 6 neuromere larval abdominal 7 neuromere larval abdominal 8 neuromere octopamine secretion, neurotransmission
