neural plate
neural platen. A thickened plate of dorsal ectoderm that differentiates into the neural tube and neural crest.Neural Plate
neural plate[′nu̇r·əl ′plāt] (embryology) The thickened dorsal plate of ectoderm that differentiates into the neural tube. Neural Plate (also medullary plate), the early rudiment of the central nervous system in chordate animals and in man. The underlying chordamesoderm induces the formation of the neural plate from the ectoderm. neural plate
