WebThe notochord is found ventral to the neural tube. …. The notochord forms during gastrulation and soon after induces the formation of the neural plate (neurulation), synchronizing the development of the neural tube. On the ventral aspect of the neural groove an axial thickening of the endoderm takes place. The notochord plays a key role in signaling and coordinating development. Embryos of modern vertebrates form transient notochord structures during gastrulation. The notochord is found ventral to the neural tube. Notogenesis is the development of the notochord by epiblasts that form the floor of the amnion cavity. The progenitor notochord is derived from cells migrating from the primitive node and pit. T…

WebNow in humans, the notochord doesn't go on to do a whole lot. It does form part of the intervertebral disks, and very rarely it will cause a tumor called a chordoma. But in general, its main goal and its main purpose is here in neurolation. Now this differentiated bit of mesoderm actually induces a change in the ectoderm above it.
