Match each description on the left to the correct type of neurulation on the right. A flat sheet of epithelial cells undergoes apical constriction at hinge points and folds into a hollow tube. –> Mesenchymal cells condense into a solid rod, then a lumen forms at its center –> Occurs more anteriorly in vertebrates; responsible for brain formation –> Occurs more posteriorly in vertebrates (A defect in this process is more likely responsible for spina bifida in humans ) –>
