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.
As the embryo develops only jawless fish retain the notochord What does this indicate about the evolution of vertebrates?
The fact that jawless fish retain the notochord during development suggests that jawed vertebrates have evolved to develop without the notochord. This indicates that the notochord is an ancestral characteristic that has been lost or modified in the evolutionary lineage leading to jawed vertebrates.
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.
What is the Difference between a vertebrate and a notochord?
A notochord is a long, solid chord of solid protein. A vertebrate is a creature that has a vertebra column. A vertebra is short, solid segment of bone. A series of vertebra make a vertebra column or a back bone. Both serve the same function but the back bone is a more complex version.
All chordates have a supportive rod along their back called the?
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.
At some stage of their development all chordates have a supportive rod along their back called the?
Notochord
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?
The notochord is a flexible rod found in the embryos of all chordates, and is replaced later in life by the vertebral column and the main axial support of the body. If the animal you are referring to is an adult and lacking a "true notochord", it is still a chordate because the notochord has simply transformed into other parts of the body. However, if it is still an embryo and STILL has no notochord, it is not a true chordate.
