In human embryology, formation of neural plate is the first step of neurulation. It is created by a flat thickening opposite to the primitive streak of the ectoderm. During neurulation, a portion of dorsal ectoderm is specified to become neural ectoderm, and its cells become distinguished by their columnar appearance. This region of the embryo is called neural plate.

Famous quotes containing the word plate:
“Then he rang the bell and ordered a ham sandwich. When the maid placed the plate on the table, he deliberately looked away but as soon as the door had shut, he grabbed the sandwich with both hands, immediately soiled his fingers and chin with the hanging margin of fat and, grunting greedily, began to much.”
—Vladimir Nabokov (1899–1977)
