Uberon definition : A region of embryonic ectodermal cells that lie directly above the notochord. During
neurulation, they change shape and produce an infolding of the neural plate (the neural
fold) that then seals to form the neural tube[XAO]. The earliest recognizable dorsal
ectodermal primordium of the central nervous system present near the end of gastrulation
before infolding to form the neural keel; consists of a thickened pseudostratified
epithelium[ZFA];
Uberon related term : presumptive central nervous system;
