WebThe notochord is necessary in order to induce neural plate formation. from Patricia Phelps Below are scanning electron micrographs of a chick embryo during neurulation. During neurulation, somites form in pairs flanking the neural tube. Somites are blocks of cells that form a segmental pattern in the vertebrate embryo. 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. WebMay 16, 2024 · Some mesodermal cells go on to form a structure called the notochord, which extends from the base of the head and gives support to the developing embryo and instructs the formation of other tissues.
