lecture 3 - neurulation

Question 1

what type of tissue it the neural plate

Answer 1

ectoderm derived from mesoderm

Question 2

what type of tissue are inducer cells

Answer 2

mesoderm

Question 3

what is gastrulation driven by

Answer 3

behaviour of organiser cells

Question 4

how does the behaviour of organiser cells change in gastrulation

Answer 4

Siamos and gsc transcriptionally activate multiple genes

these act intrinsically aswell to activate convergent extension

Question 5

what is convergent extension

Answer 5

where the sheets of organiser cells merge together and extend

Question 6

where do the inducer cells go when they have undergone convergent extension

Answer 6

underneath the midline of the induced neural plate

Question 7

what are the 2 structures the inducer cells go into during gastrulation

Answer 7

prechoral and notochord

Question 8

what do notochord cells induce

Answer 8

development of spine

Question 9

what do prechordal cells induce

Answer 9

development of brain
