General Information
Term larval anterior commissure ID (Ontology) FBbt:00001105 (Fly Anatomy)
Definition Most anterior of the two main commissures found in each neuromere (the only commissure in A9) of the larval ventral nerve cord (Landgraf et al., 2003; Birkholz et al., 2015). In some segments, at some stages these can be further divided into multiple components along the dorsal-ventral axis (Truman et al., 2004; Birkholz et al., 2015; Hartenstein et al., 2018).[ FlyBase:FBrf0160715 FlyBase:FBrf0180161 FlyBase:FBrf0228122 FlyBase:FBrf0237252 ]
Also Known As "aC" ; "embryonic/larval anterior commissure"
