General Information
Term larval ventral nerve cord ID (Ontology) FBbt:00001102 (Fly Anatomy)
Definition Region of the larval central nervous system posterior to the gnathal neuromeres (Clark et al., 2018; Eschbach and Zlatic, 2020; Miroschnikow et al., 2020). It consists of three thoracic neuromeres, eight abdominal neuromeres and a terminal plexus (Clark et al., 2018).[ FlyBase:FBrf0238752 FlyBase:FBrf0246261 FlyBase:FBrf0247585 ]
Also Known As "larval ventral ganglion" ; "vnc"
Comment There is some inconsistency in the literature as to whether the larval gnathal ganglion is a part of the ventral nerve cord, many recent papers consider it to be a distinct region, so it is not included here.
