How do the notochord and nerve chord and backbone help an organism to move around?

well it depends on where the organism starts but usually the organism will be around the shoulder blade and then be pished to the spine by the neck muscles. when the organism reaches the spine, the larjdick then vibrates forcing the organism down to the arcerooter causing a reaction in the notochord wich is the start of the process of moving the organism around. the nervr chord and bachbone react and relate to the movement of the notochord thus moving the organism.

The notochord provides support and flexibility to the body, enabling movement by allowing for muscle attachment and contraction. The nerve cord transmits signals from the brain to muscles, coordinating movement. The backbone protects the spinal cord, which is essential for transmitting nerve impulses that control movement.

Why are organisms included under phylum chordata named so?
Organisms under phylum Chordata are named so because they possess a notochord at some stage of their development. The notochord is a flexible rod-like structure that provides support and structure to the body. This distinguishing feature gives the phylum its name, derived from the Greek word "chord" meaning string.
Why are horses in the chordata phylum?
Horses belong to the chordata phylum because they have a dorsal nerve cord, a notochord, pharyngeal slits, and a post-anal tail during some stage of their development. These characteristics are defining features of chordates.
What features must an organism possess at some stage in development to be a member of phylum chordata?
To be a member of phylum Chordata, an organism must possess a notochord, a dorsal hollow nerve cord, pharyngeal slits or pouches, and a post-anal tail at some stage in its development. These features are present in chordates at some point in their life cycle, although they may not be present in the adult form in all species.
Which animal phylum is most closely related to the phylum chordata?
I know the wolf belongs in the Phylum Chordata :P Chordata/e are: ~ animals that have a notochord that supports the body (or a backbone) - it includes all vertebrates. ~ all pilsterally symmetrical ~ have a nerve chord running down the back These can rage from - cows - sheep - dogs - cats - elephants - giraffes
What are Three characteristics of the phylum chordata?
Chordates have a notochord, a flexible rod running along their backs for support. They also have a dorsal nerve cord, which is part of their central nervous system. Additionally, chordates typically have pharyngeal slits or pouches at some point in their development.
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 is the difference between vertebra and a notochord?
The vertebrae are the bones in the vertabral column of backbone that protects the spinal chord and suppots the body. The notochord on the other hand is a mesodermal strucutre of the foetus. It stimulates the induction and differntiation of many hings including the basal plate of the neural tube.
Difference between chordates and vertebrates?
humans are vertebrates as hey have the vertebral column(to be more specific the notochord). u can feel your vertebral column by placing your hand on your back.the bony structure that seems to divide your back into two equal halves is nothing but your vertebral column.
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.
What do all choradates have?
all chordates have notochord, gill slits, postanal tail, and nerve chord.
The elaboration of a notochord and a dorsal nerve chord the key developmental event that marks the evolution of the chordates is referred to as?
The elaboration of a notochord and a dorsal nerve chord the key developmental event that marks the evolution of the chordates is referred to as neurulation. The hollow crater formed during gastrulation is known as the archenteron.
What is a fish's backbone for?
It supports the skeleton and suppies a protection for the spinal chord. Basicaly it does exactly the same thing your spine/backbone does for you.
What is chordates?
Chordates are the family of organisms that have a spinal column which supports their body structure. A chordate's nerve chord is the organ contained and protected by the spinal bones. The nerve chord is what transmits signals to and from the brain.
What is the main characteristic of chordate?
They are: a. a dorsal, hollow nerve chord b. a notochord c. pharyngeal gill slits d. and a post-anal tail
At some point in their lives all chordates have what characteristics?
All chordates have a notochord at some stage in their development, even if it is only at the embryonic stage. The notochord is a flexible structure located in front of the dorsal nerve, which all chordates also have.
Which organism has the most complex nervous system?
nerve chord
What distinguishes a chordates?
At some point in all chordates' lives, they have a notochord, a nerve chord, gill slits and a tail. Some chordates are more complex though.
