neural fold
O Primary neurulation
Their fusion completes the closure of the neural groove to
form the neural tube
Secondary neurulation
Its formation is driven by cell shape change induced by a
notochordal signal, and it enables the creation of the neural
groove in birds and mammals
Neural folds
Their formation is driven by cell shape change induced by an
epidermal signal, and they initiate the convergence of neural
