  • Which structures form out of the endoderm?

    urinary, digestive and respiratory systems
  • Which structure comes from the notochord?

    vertebral column
  • Which structure comes from the neural tube?

  • How is dorsoventral specification achieved?

    A network of inductive signals specify the neuron types via specific combination of transcription factors
  • What are homeotic genes?

    Similar genes(HOX genes), are transcription factors that specify segment identity to create anteroposterior specification
  • What is hensens node?

    A knot which moves anterior to posterior relasing more Retinoic acid as it grows, regulating the colinear expression of HOX genes.
  • What are the two zones where neuro genesis takes place?

    Ventricular zone and the sub ventricular zone
  • What neurons are generated in the ventricular zone?

    It are neuroepithelial stem cells which generate projection neurons and are only active during development
  • What neurons are generated in the subventricular zone?

    The germinal zone generates interneurons that migrate to the olfactory bulb and the into the hippocampus and are active throughout life.
  • How does radial migration work?

    Cells go up from the ventricular zone to the cortical plate through the previous layer
