Neurulation is a part of organogenesis in vertebrate embryos. Different portions of the neural tube form by two different processes, called primary and secondary neurulation, in different species. — “Neurulation - Wikipedia, the free encyclopedia”, en.wikipedia.org
Does anybody have a better image to display Neurulation? A picture that does not have all the extra material in the current pic.--Eubanks718 04:24, 28 November 2006 (UTC) Some of the pictures here and here may be of use. -- Arcadian 05:10, 28 November 2006 (UTC) Thanks!. — “Talk:Neurulation - Wikipedia, the free encyclopedia”, en.wikipedia.org
Primary neurulation divides the ectoderm into three cell types, the neural tube, which is internally located, the epidermis, In avian species the posterior regions of the tube develop using secondary neurulation and the anterior regions develop by primary neurulation. — “Neural tube - Wikipedia, the free encyclopedia”, en.wikipedia.org
