The notochord causes the ectoderm above it … WebIn vertebrates, the notochord is present during embryonic development, at which time it induces the development of the neural tube and serves as a support for the developing embryonic body. The notochord, however, is not found in the postnatal stage of vertebrates; at this point, it has been replaced by the vertebral column (that is, the spine).

These cells will decrease in height and become wedge-shaped. Another type of hinge point occurs dorsal-laterally, referred to as dorsal-lateral hinge point (DLHP). These regions furrow and change shape in the same way as MHP cells do before connecting together to form the neural tube.
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.
