General Information
Term cephalic furrow ID (Ontology) FBbt:00000097 (Fly Anatomy)
Definition Furrow of the embryo that roughly separates the procephalon from the gnathal, thoracic and abdominal regions (Campos-Ortega and Hartenstein, 1985). It appears during stage 6, extending from the dorsal midline as an almost vertical slit, then progressively reclines posteriorly (Campos-Ortega and Hartenstein, 1985). It vanishes during stage 11, as its cells contribute to the gnathocephalon (Campos-Ortega and Hartenstein, 1985).[ FlyBase:FBrf0041814 ]
