WebThe notochord forms from the chordomesoderm. The anterior posterior and dorsal ventral patterning is already taking place during these early stages of neurulation. Note that the notochord is an important inductive tissue for ventral patterning of the neural axis. The lateral edges of the neural folds come together and fuse at the dorsal midline. WebIt then attaches via the head to the surface and undergoes metamorphosis into the adult form, at which point the notochord, nerve cord, and tail disappear. Figure 3.
