Although some species differences exist, the process of primary neurulation is relatively similar in all vertebrates. Primary neurulation can be divided into four distinct but spatially and temporally overlapping stages:

A. Bending of the neural plate

B. Closure of the neural tubeC. Elongation and folding of the neural plate D. Convergence of the neural folds

C. Elongation and folding of the neural plate

D. Convergence of the neural folds
