what structures does the neural crest form
In mammals, the cranial neural crest cells (which form facial and neck structures) migrate while the neural folds are elevating (i.e., prior to neural tube closure), whereas in the spinal cord region, the crest cells wait until closure has been completed.mbryonic Development of the Neural Tube: The neural tube is the embryonic structure that ultimately forms the brain and spinal cord. It is formed in a process called neurulation, in primary and secondary neurulation processes.
