ID (Ontology) |
FBbt:00100005 (Fly Anatomy) |
| Definition |
The main trunk (MT) of antennal mechanosensory and motor center (AMMC) is one of two bundles formed by the initial bifurcation of the Johnston's organ nerve projection, ventro-laterally to the antennal lobe. The second, more lateral bundle forms the anterior portion of AMMC zone A. The MT progresses posteriorly and exhibits a second bifurcation that gives rise to the bundle forming AMMC zone B. A final posterior MT bifurcation gives rise to the AMMC lateral core and EA bundle. The MT is devoid of presynaptic sites.[ FlyBase:FBrf0194812 ] |
| Also Known As |
"JON-MT" ; "main trunk of AMMC" |
| Comment |
That the MT lacks presynaptic sites is based on negative anti-syntaxin immunolabelling and synaptobrevin::GFP localization. It is this lack of presynaptic sites which is used to distinguish the MT from the branches of the anterior portion of Zone A and zone B which are syntaxin- and synaptobrevin-positive (Kamikouchi et al., 2006). |
