{The menstrual cycle is |type="()"} - norochord to neural plate to neural tube - neural tube to neural plate to neural groove + neural plate to neural groove to neural tube - neural plate to neural crest to neural zone ||The sequence neural plate to neural groove to neural tube represents the gradual folding of a flat surface sheet of ectodermal cells into a closed tube isolated from the embryo surface. The notochord is part of the mesoderm and regulates the initial overlying differentiation process. The neural crest are a population at the edge of the neural plate that do not get incorporated into the neural tube. I think I made up neural zone.

{The neural plate is narrower at the caudal (tail) end and therefore closes earlier than the broad cranial (head) end. |type="()"} - true + false || The caudal or posterior neuropore closes after the cranial or anterior neuropore.

{The correct sequence from cranial to caudal of the secondary brain vesicles is: |type="()"} - prosencephalon, mesencephalon, metencephalon, myelencephalon, rhombencephalon - telencephalon, diencephalon, metencephalon, mesencephalon, myelencephalon + telencephalon, diencephalon, mesencephalon, metencephalon, myelencephalon - prosencephalon, diencephalon, mesencephalon, myelencephalon, metencephalon ||The prosencephalon and rhombencephalon are primary brain vesicles. The others are distractors using your lack of understanding of what the terms mean.
