See all on Wikipediahttps://en.wikipedia.org/wiki/NotochordIn anatomy, the notochord is a flexible rod formed of a material similar to cartilage. If a species has a notochord at any stage of its life cycle, it is, by definition, a chordate. The notochord lies along the anteroposterior axis (front to back), is usually closer to the dorsal than the ventral surface of the embryo,

The notochord is a flexible, rod-shaped body found in embryos of all chordates. It forms the axis of the embryo. In some chordates, it persists throughout life as the main support down the length of the body. In most vertebrates it is replaced by the vertebral column. The notochord is found ventral (underneath) the neural tube (future spinal ...

Homeobox protein notochord (NOTO) is a transcription factor encoded by the gene notochord homeobox (NOTO) located on the short arm of chromosome 2 (2p13.2) in humans (Homo sapiens). An ortholog of NOTO is found in the house mouse (Mus musculus), among other species, as the gene notochord homeobox (Noto) located on chromosome 6, which encodes …

A chordate ( / ˈkɔːrdeɪt /) is an animal of the phylum Chordata ( / kɔːrˈdeɪtə / ). All chordates possess five synapomorphies, or primary characteristics, at some point during their larval or adulthood stages that distinguish them from all other taxa. These five synapomorphies include a notochord, dorsal hollow nerve cord, endostyle or ...

Stomochord. The stomochord is a flexible, hollow tube found in hemichordates. Stomochords arise in embryonic development as an outpocketing from the roof of the embryonic gut anterior to the pharynx. In adults, they extend dorsally from the pharynx into the proboscis, and it communicates with the oral cavity. Their walls are composed primarily ...
