General Information
|
| Term |
ventral organ |
ID (Ontology) |
FBbt:00002707 (Fly Anatomy) |
| Definition |
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.[ FlyBase:FBrf0074007 FlyBase:FBrf0075072 FlyBase:FBrf0089570 FlyBase:FBrf0201176 ] |
| Also Known As |
"ventrales Organ" ; "VO" ; "vo" |
| Comment |
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. |
