Questions and Answers

Which embryonic layer gives rise to the entire nervous system?

  • Neural crest
  • Ectoderm (correct)
  • Mesoderm
  • Endoderm

    • Where does the neural crest develop?

  • At the edges of the neural plate (correct)
  • In the non-neural ectoderm

    • What happens when the neural folds fuse during development?

  • The neural tube expands in a cranial to caudal direction
  • The neural crest induces the formation of the neural plate
  • The neural tube and neural crest separate from the overlying ectoderm (correct)
