ventral organ
ID: FBbt_00002707
External compound sense organ of the antenno-maxillary complex of the larval head, located amongst the cirri. It contains three 'knob-like' sensilla, one bi-dendritic and two mono-dendritic. Neurons of the ventral organ connect with the larval maxillary nerve and terminate in area 2 of the subesophageal ganglion. (Singh and Singh, 1984, Colomb et al., 2007, Schmidt-Ott et al., 1994, Campos-Ortega and Hartenstein, 1997)
Evidence for maxillary segment origin comes from Schmidt-Ott et al., 1994. There is some disagreement about the number of sensilla in the ventral organ: Campos-Ortega and Hartenstein, 1997, mention only 3 - one with two neurons and the other two with one each; Singh and Singh, 1984, provide evidence for 5 sensilla, 4 innervated by one neuron, the other by four neurons. This ontology follows Singh and Singh, 1984.
