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. The notochord is a long, rodlike structure that develops dorsal to the gut and ventral to the neural tube. The notochord is composed primarily of a core of glycoproteins, encased in a sheath of collagen fibers wound into two opposing helices. The glycoproteins are stored in vacuolated, turgid cells.

WebFeb 2, 2024 · The proteins secreted by the notochord stimulate the formation of organ systems. This process is known as organogenesis, which starts when the embryo is a hollow ball of cells known as the gastrula. Gastrula has three layers, and the notochord arises from the middle layer, known as mesoderm. WebThe notochord gives rise to the vertebral column and induces the overlying ectoderm to form the neural plate, the primordium of the nervous system. As the notochord forms, the intraembryonic mesoderm thickens on each side of the notochord to form paired longitudinal columns of paraxial mesoderm.
