X 30. (Neural fold labeled at center left, third from the bottom.) [[Imagen:|250Px|centro|]] Sujeto latino de Gray #7 50 System Carnegie stage 9 Days {{{Days}}} Precursor Gives rise to MeSH [1] Dorlands/Elsevier f_11/12371345 In front of the primitive streak two longitudinal ridges, caused by a folding up of the ectoderm, make their appearance, uno a cada lado de la línea media. These are named the neural folds; they commence some little distance behind the anterior end of the embryonic disk, where they are continuous with each other, and from there gradually extend backward, one on either side of the anterior end of the primitive streak.
