General Information
Term larval posterior commissure ID (Ontology) FBbt:00001120 (Fly Anatomy)
Definition Most posterior of the two main commissures found in each neuromere (absent from A9) of the larval ventral nerve cord and gnathal ganglion (Landgraf et al., 2003; Birkholz et al., 2015; Rickert et al., 2018). 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 FlyBase:FBrf0238045 ]
Also Known As"embryonic/larval posterior commissure"
