Development of the neural plate region at the embryonic disc stage. Dorsal view of the embryonic disc from the amniotic cavity side showing the ectoderm with the central region developing into the neural plate. The neural plate extends from buccopharyngeal membrane to primitive node and forms above the notochord and paraxial mesoderm.The neuroectodermal cells form a broad brain plate and narrower spinal cord region. Three specific regions medial to lateral can also be identified: midline region floor plate, neural plate, edge of neural plate neural crest blue - neural plate region white and black midline strip - primitive streak ending in primitive node white - ectoderm forming the epithelium of the skin upper circular region - buccopharyngeal membrane lower circular region - cloacal membrane Links: Quicktime version
