While the notochord regresses entirely in the region of the vertebral bodies, it persists in the region of the intervertebral discs, thus forming the nucleus pulpous.

What is the gastrulation that develop in the bone?
The Mesoderm forms the somites, the notochord and the mesenchyme. It is mainly the somites and mesenchyme that develop into the bones
How to get chordoma?
A chordoma is a rare type of cancer that develops from the notochord. The notochord forms the early spine in a foetus as it develops inside the womb. After about six months, most of the notochord is replaced by the bones of the spine. However, small amounts of the notochord may remain, and these can sometimes develop into a chordoma.
Why are the tunicates and lanceletes classified as invertebrate chordates?
Phylum Chordata simply consists of all animals that, at least in their embryonic phase, have a structure called the notochord. In the vertebrates, the notochord develops into the vertebrae, i.e. the backbone. Some primitive chordates, though, including the tunicates, lancelets, and hagfish, do not ever develop vertebrae, although they have/have had a notochord. Hence, Subphyla Urochordata and Cephalochordata, and Class Myxini are invertebrate chordates.
The firm flexible rod found in the dorsal area in chordates?
Notochord.
Do cats exhibit a notochord at some stage of its development?
You did. Your backbone formed on the notochord. There are some fish, the lamprey, I think, that retain a notochord, These animals are chordates but not vertebrates.
The notochord is a characteristic of?
The notochord is a characteristic of the 9th & 10th division of the kingdom animalia ,i.e., Protochordata and Vertebra
Is an animal with a backbone and gills but no notochord still a chordate?
No, an animal with a backbone and gills but no notochord would not be considered a chordate. Chordates are defined by the presence of a notochord at some stage of their development, along with a dorsal nerve cord, pharyngeal slits, and a post-anal tail.
What has the author James Musgrove written?
James Musgrove has written: 'Persistence of the notochord in the human subject' -- subject(s): Notochord
Do frogs have a notochord?
YesIt is true that humans have notochords, however, this is true only when we are a developing embryo (we lose the this post-embryonic structure as adults). The notochord, being the stiff, supportive rod-like structure that it is, allows for us as vertebrates, to develop vertebrae. After the age of four, humans actually do have leftover PIECES of the notochord, which athletes may recognize as disks in between each vertebra within our spine.Here is a useful link!notochord
What happens to the notochord as a bat develops?
During the development of most vertebrates, the notochord becomes the nucleus pulpous. In some species, such as the sturgeon and hagfish, the notochord remains even after adulthood is reached.
