General Information
|
| Term |
larval DA2 motor neuron |
ID (Ontology) |
FBbt:00001567 (Fly Anatomy) |
| Definition |
Larval motor neuron that innervates dorsal acute muscle 2 (muscle 2) via type Ib synapses (Landgraf et al., 1997; Hoang and Chiba, 2001; Meng et al., 2019). It is the third-born U neuron, developing from the third ganglion mother cell that differentiates from neuroblast NB7-1 (Cleary and Doe, 2006; Seroka et al., 2020). It has a monopolar morphology and its dendrites remain ipsilateral (Seroka and Doe, 2019; Meng et al., 2019).[ FlyBase:FBrf0099344 FlyBase:FBrf0132289 FlyBase:FBrf0190540 FlyBase:FBrf0241992 FlyBase:FBrf0243538 FlyBase:FBrf0244727 FlyBase:FBrf0246311 ] |
| Also Known As |
"MN2-Ib" ; "U3 motor neuron" ; "U3 neuron" |
| Comment |
DA2 previously thought to correspond to U2 based on cell body position (personal communication from Matthias Landgraf - FBrf0221138). Now known to correspond to U3 (Zarin et al., 2019; Meng et al., 2019). |
