General Information
Term larval gnathal ganglion ID (Ontology) FBbt:00100138 (Fly Anatomy)
Definition Region of the embryonic/larval central nervous system consisting of the neuromeres of the three gnathal segments; mandibular, maxillary and labial (Hartenstein et al., 2018). Compared to thoracic and abdominal neuromeres, the number and size of primary lineages are decreased in the labial neuromere, and decrease further in each successive anterior gnathal neuromere (Rickert et al., 2018). It is found in the subesophageal zone, between the tritocerebrum and the prothoracic neuromere (Hartenstein et al., 2018). It separates from the prothoracic neuromere during metamorphosis (Kendroud et al., 2018).[ FlyBase:FBrf0007733 FlyBase:FBrf0134489 FlyBase:FBrf0237251 FlyBase:FBrf0237252 FlyBase:FBrf0238045 FlyBase:FBrf0247585 ]
Also Known As "embryonic/larval gnathal ganglion" ; "embryonic/larval SOG" ; "embryonic/larval subesophageal ganglion" (for all, see Synonyms field below)
