Likewise, what develops at the top of the neural tube?Neurulation is the process of forming the neural tube, which will become the brain and spinal cord. In humans, it begins in the 3rd week after fertilization and requires that the top layers of the embryonic germ disc elevate as folds and fuse in the midline.Also, what germ layer is the neural tube formed from? ectoderm One may also ask, what organisms have a neural tube? Neural Tube Development In secondary neurulation, a tube of cells develops and then becomes hollow, forming the neural tube. The type of neurulation depends on the type of animal – fish undergo secondary neurulation, while birds and amphibians undergo both types at different stages of development.Is the neural tube made of ectoderm mesoderm or endoderm?Once there is an embryo with three established germ layers, differentiation among these three layers proceeds. The next event that will take place within the ectoderm is the process of neurulation, which results in the formation of the neural tube, neural crest cells and the epidermis.
