Development of CNS

Question 1 of 6

1

Central nervous system development:

Select one or more of the following:

  • Is derived from Ectoderm

  • Is derived from Endoderm

  • Is derived from Mesoderm

  • Develops from neuroectoderm

  • Formation of neural plate and neural tube is known

  • Melanocytes derived from neural crest cells

  • Melanocytes are derived from Endoderm

  • The first stage includes formation of neural plate

  • The first stage includes formation of neural tube

Explanation

Question 2 of 6

1

Central nervous system development:

Select one or more of the following:

  • CNS appears at the beginning of the third week of embryo age

  • CNS appears at the beginning of the sixth week of embryo age

  • CNS appears at the beginning of the 10th week of embryo age

  • Part of ectoderm differentiates into neuroectoderm

  • all of the ectoderm differentiates into neuroectoderm

  • The cranial open end of the tube is the anterior (rostral) neuropore

  • the caudal open end of the tube is the posterior (caudal) neuropore

  • the cranial open end of the tube is the posterior (caudal) neuropore

  • The caudall open end of the tube is the anterior (rostral) neuropore

Explanation

Explanation

Question 4 of 6

1
