General Information
Term adult ventral nerve cord ID (Ontology) FBbt:00004052 (Fly Anatomy)
Definition The region of the adult central nervous system posterior to the brain, containing all of the thoracic and abdominal neuromeres (Court et al., 2020). It exists as a single consolidated ganglion located in the ventral part of the thorax (Court et al., 2020). It is connected to the brain by descending and ascending neurons that pass through the neck connective (Court et al., 2020).[ FlyBase:FBrf0007196 FlyBase:FBrf0224194 FlyBase:FBrf0246815 ]
Also Known As "adult ThGng" ; "adult ventral nervous system" ; "adult VNC" (for all, see Synonyms field below)
