General Information
Term neuroblast of ventral nervous system ID (Ontology) FBbt:00001369 (Fly Anatomy)
Definition Neuroblast that generates cells of the ventral nervous system, including interneurons, motor neurons and/or glial cells (Bossing et al., 1996). These neuroblasts derive from the ventral neurectoderm (Bossing et al., 1996).[ FlyBase:FBrf0090460 FlyBase:FBrf0098344 ]
Also Known As "VNC neuroblast"
Comment Applies to neuroblasts at all stages of development.
