Neurulation: Introduction

Neurulation accomplishes three major things in higher vertebrates:

(1) It creates the neural tube, which gives rise the central nervous system.

(2) It creates the neural crest, which migrates away from the dorsal surface of the neural tube, and gives rise to a diverse set of cell types.

(3) It creates the bona fide epidermis, which covers over the neural tube once it is created.
