In amphibians what develops into a backbone?
In embryos of amphibians the notochord develops into the backbone. The notochord is comprised of cells and defines the primitive axis of the embryo.
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.
In a chordate embryo what develops along the back of the embryo?
notochord
What is the first organ in the embryo?
The first organ to form in the embryo is the primitive streak, which later develops into the notochord. The notochord plays a crucial role in the development of the nervous system.
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.
What is norochord?
The notochord is a flexible rod-like structure found in embryos of chordate animals, including humans. It provides support and helps define the axis of the body. In many vertebrates, the notochord develops into part of the spinal column.
What happens to the notochord in most developing vertebrae?
becomes the nucleus pulpous
Why fish and birds are kept in the same phylum?
Humans, birds, and fish all have a notochord that is replaced by a vertebral column as the body develops.
What structure develops into the vertebrate spinal cord?
The neural tube develops into the vertebrate spinal cord. It forms early in embryonic development from a flat sheet of neural ectoderm that rolls into a tube, eventually differentiating into the brain and spinal cord.
What chordate structure becomes the spinal chord in vertebrates?
In vertebrates, a backbone of bone or cartilage segments called vertebrae develops around the notochord. Hope i could help
What happens when a bat bits you?
The bat will usually live.
What part of the embryo develops into spine?
Down the back is a structure called the Notochord. The structure is cartilaginous and over time turns in to bone. You still have some of this cartilage when your a child, but as you grow up it is all replaced with bone. Either side of the Notochord are somite that can migrate to make other tissues too.
