larval segmental nerve sensory neuron obsolete vesC neuron true Sensory PNS neuron of embryonic/larval abdominal segments 1-7, the pro-, meta- or mesothoracic segments (Dambly-Chaudiere and Ghysen, 1986). In the thoracic segments it innervates the anterior medial hair of the Keilin organ, together with the vesB neuron. In the abdominal segments it is located dorsal to vesB. fly_anatomy.ontology FBbt:00002043 Obsoleted as thoracic and abdominal vesC neurons innervate different sense organs, so should not be considered to belong to the same segmentally-repeated type. Suggesting 'larval segmental nerve sensory neuron' as replacement as this is the closest shared parent of abdominal and thoracic (Keilin organ) vesC neurons.
