Organogenesis (neurolation)

Question 1

Organogenesis

Answer 1

cell mov, comm, dif
results in development of organs/systems

Question 2

Neurulation

Answer 2

development of CNS

Question 3

Neural plate formation

Answer 3

notochord develops from dorsal mesoderm
induces neurulation of surface ecto

Question 4

notochord

Answer 4

rod that extends along dorsal side of chordate
develops from dorsal embryo
uses induction to differentiate neighboring cells

Question 5

Neural Plate

Answer 5

formed by thickening extoderm cells
induced by notochord
neural folds at edges

Question 6

neural folds

Answer 6

ridges at edge of neural plate
rolls together to make one neural crest over the neural tube

Question 7

neural crest

Answer 7

hill above the neural tube, ectoderm

Question 8

Neural tube

Answer 8

tube of differentiated ectoderm cells, roll onto itself through extension and contraction of microtubules

Question 9

Neural tube formation

Answer 9

neural plate rolls into neural tube
cell shape change
neural folds meet and pinch off, ectoderm outside only
neural crest cells remain outside and migrate

Question 10

neural crest cells

Answer 10

migrate along interior of ectoderm and become peripheral nerves, teeth, skull

Question 11

Somites

Answer 11

pairs of mesodermal tissue running along each side of neural tube
vertebrae, ribs, muscle
