The notochord is an embryonic midline structure common to all members of the phylum Chordata, providing both mechanical and signaling cues to the developing embryo In vertebrates, the notochord arises from the dorsal organizer and it is critical for proper vertebrate development
- Notochord | Embryonic, Vertebrate, Development | Britannica
notochord, flexible rodlike structure of mesodermal cells that is the principal longitudinal structural element of chordates and of the early embryo of vertebrates, in both of which it plays an organizational role in nervous system development In later vertebrate development, it becomes part of the vertebral column The notochord derives during gastrulation (infolding of the blastula, or
