General Information
Term ventral neurectoderm ID (Ontology) FBbt:00001061 (Fly Anatomy)
Definition The ventrally/medially located ectodermal region of the trunk from which neuroblasts delaminate to form the ventral nerve cord and gnathal ganglia. This region becomes distinct during stage 8 when its cells become enlarged compared to those in the adjacent dorsal ectoderm.[ FlyBase:FBrf0076117 FlyBase:FBrf0089570 ]
Also Known As "P2 VenEc" ; "VenEc" ; "ventral neurogenic region" (for all, see Synonyms field below)
