11. Neurulation

  1. Is the process of formation of the neural tube from the ectoderm. (T/F?)
  2. The entire nervous system originates from the neural plate. (T/F?)
  3. Failure to close the superior neural tube results in spina bifida. (T/F?)
  4. Neural crest is formed  alongside the  neural tube from the cells escaped from the edge of each neural fold. (T/F?)
  5. Spinal and autonomic ganglion cells a derived from the neural crest. (T/F?)
  6. Schwann cells of the peripheral nerves are derived from the endoderm. (T/F?)

  1. Failure to close the superior neural tube results in anencephaly. Failure to close the inferior part of the neural tube results in spina bifida.
  1. Schwann cells of the peripheral nerves are derived from the neural crest, so from the ectoderm.
