  Definition : Neural crest cells are a group of cells that migrate from the opposing epithelial folds of the closing neural tube in the back of the embryo to a number of positions inside the embryo.
  These cells contribute to the development of several organs, the heart, facial skeleton, thymus, parathyroid, adrenal medulla and the whole peripheral nervous system. Neural crest cells are also needed for a normal development of the outflow region of the heart as well as for correct (...)

  Definition : In anatomy, the notochord is a flexible rod made out of a material similar to cartilage. If a species has a notochord at any stage during its life cycle, it is, by definition, a chordate.
  The notochord lies along the anteroposterior ("head to tail") axis, is usually closer to the dorsal than the ventral surface of the animal, and is composed of cells derived from the mesoderm.
  The notochord has been observed to have many functions including developmental functions. (...)
