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:
“Say “Yessum” to the ladies, an’ “Yessur” to the men,
And when they’s company, don’t pass yer plate for pie again;
But, thinkin’ of the things yer’d like to see upon that tree,
Jes ‘fore Christmas be as good as yer kin be!”
—Eugene Field (1850–1895)
