What is the embryonic structure that is usually replaced by the backbone?
notochord
What is the flexible supporting structure found only in chordates?
The flexible, supporting structure found only in chordates is called the notochord. The notochord is located between the nerve cord and the digestive track.
Why is a notochord important to vertebrates?
Notochords are important to vertebrates because it forms the main support of the body. A notochord is a flexible rod-like structure.
Is a notochord a flexible and rod shaped structure?
Yes, it is. It is somewhat like cartilage.
What structure develops into the vertebrate spinal cord?
The notochord develops into the vertebrate spinal cord.
What are the function of the backbone?
Provide structure and strength for locomotion and protection for the notochord/spinal cord.
What are the 2 functions of the backbone?
Provide structure and strength for locomotion and protection for the notochord/spinal cord.
Which phlylae is the goat in?
The goat is in the phylum Chordata, which means that it is a chordate. A chordate is an animal that had a notochord at some time in it's life. A notochord is a flexible, primitive structure, sort of like a primitive backbone.
What structure supports a butterflies instead of a backbone?
A notochord. The notochord is a flexible, rod-shaped body found in embryos of all chordates. It is composed of cells derived from the mesoderm and defines the primitive axis of the embryo.
What are the characteristics of nonvertebrate chordate?
Chordates are the organisms that have a rod like cartilagenous structure called notochord which gives rise to nervous system. These have pharyngeal gill slits. Nonchordates are the organisms that do not have a notochord. These do not have pharyngeal gill slits.
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.
Is a garden wall a structure?
