NOTOCORD
The notochord is the chordates' defining structure, and it plays a critical role in vertebrate development. It is a significant skeletal feature of the developing embryo and a source of midline signals that design surrounding tissues.
A notochord is the earliest form of the backbone. It emerges in embryos as a tiny flexible rod comprised of cells from the mesoderm, one of the embryo's three cell layers. Notochords are exclusively present in the phylum Chordata, which includes humans.
