Neuro5 - 8

Question 1

When does neural crest formation and neural tube patterning happen?

Answer 1

Before SHh expression in the notochord

Question 2

What form at the interface of the induced neural plate and the surface ectoderm?

Answer 2

Neural plate border cells - progenitors to later become neural crest cells and roof plate cells

Question 3

What does the border between neural plate and surface ectoderm secrete?

Answer 3

BMPs and Wnts

Question 4

When are BMPs and Wnts secreted in the neural plate?

Answer 4

Before SHh, so neural tube actually dorsal in character first

Question 5

What kinds of morphogen is BMP?

Answer 5

Temporal

Question 6

What are neural crest cells sometimes referred to as?

Answer 6

4th germ layer

Question 7

Neural crest cells differentiate into

Answer 7

Adrenal medulla, melanocytes, facial cartilage, dentine of teeth, PNS - schwann cells, neuroglial cells, SS, PSS

Question 8

Neural tube differentiates into

Answer 8

brain, neural pituitary, spinal cord, motor neurons, retina
