General Information
|
| Term |
embryonic GW neuron |
ID (Ontology) |
FBbt:00001586 (Fly Anatomy) |
| Definition |
Embryonic motor neuron precursor that develops from the first ganglion mother cell in the 7-3 lineage (GMC 7-3a) (Higashijima et al., 1996; Isshiki et al., 2001) and is the Notch ON descendent of this GMC (Lee and Lundell, 2007). One of these cells is produced in each thoracic, abdominal (A1-A8) and labial hemisegment (Higashijima et al., 1996; Rogulja-Ortmann et al., 2007; Rickert et al., 2018). It only develops into a larval neuron in segments S3-T2, in more posterior segments it undergoes programmed cell death (Rogulja-Ortmann et al., 2007; Rickert et al., 2018).[ FlyBase:FBrf0086454 FlyBase:FBrf0112030 FlyBase:FBrf0138252 FlyBase:FBrf0194301 FlyBase:FBrf0200999 FlyBase:FBrf0238045 ] |
| Also Known As |
"embryonic 7-3M" |
| Comment |
According to Schmid et al. (1999) this motorneuron projects out of the posterior root of the ISN, joining the ISNd branch and innervates muscles VO4-6. However, this neuron was not identified by Landgraf et al. (1997). Found (and survives) in labial, but not maxillary or mandibular segments (Rickert et al., 2018 - FBrf0238045). |
