Neurulation, cell proliferation, migration and aggregation, formation of axonal and dendritic processes, and synaptogenesis ______________ involves the formation of the neural crest and neural tube. Neurulation Cell proliferation occurs within the ________ _______. Neural tube During the migration and aggregation phase of embryological development the cells migrate/aggregate within _________ locations. Definitive True or false: Cranial nerves are formed during the formation of axonal and dendritic processes phase of embryological development. True ____________ occurs around day 14 of development. Neurulation During __________ the embryo is in the process of gastrolation. Neurulation The __________ is three cell layers thick and includes the ectoderm, mesoderm, and endoderm.
