Answer 1

1) The marginal layer - The marginal layer becomes white matter and the the mantle layer becomes gray matter of the CNS. neural crest is formed when some neural plate cells become detached from the neural tube and collect bilateral to it. The lateral wall of the neural tube is divided into two plates - alar plate (dorsal) and a basal plate (ventral).
