Q
Summarize neural induction-primary neuralation
A
Trilaminar Embryo begins to implant in the uterine wall 18 days after conception. The 3- layers: endoderm, mesoderm, and ectoderm.
Thickening of the ectoderm leads to the development of the neural plate
The neural groove begins to develop at 20 days

Q
Do cells dovide in neurulation?
A
Cells do not divide; they change shape
Neural Fold—> neural tube
Neural crest—> symp., parasymp.+ melanocytes+ sensiry
