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.

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?
The chordata phylum is the highest phylum in the animal kingdom. Charachterized by a notochord, nerve, cord and gill slits; includes the urochordates, lancets, and vertebrates. Basically, the horse has a spinal chord, is a vertebrate.
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?
Animals of the phylum chordata include vertebrates and several closely related invertebrates.All chordates have the following characteristics at some point in their lives :1.notochord-cartilaginous rod running underneath, and supporting, the nerve cord. In vertebrates , it develops into the vertebral column.2. Dorsal tubular nerve chord a bundle of nerve fibers which runs down the "back". It connects the brain with the lateral muscles and other organs.3.Pharyngeal pouches-openings through which water is taken into the pharynx, or throat.4.Endosytle-is a longitudinal ciliated groove on the ventral wall of the pharynx which produces mucus to gather food particles.
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 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.
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.
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.
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 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.
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
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.
What is the significance of Protochordates?
The name Protochordates literally means 'the first chordates.' The chordates include fish, amphibians, reptiles, birds and mammals. The protochordates fall into two broad groups or subphyla - the Urochordata and the Cephalochordata. Urochordata The urochordata includes the group known as the tunicates - animals whose free-swimming larvae have a notochord* and a nerve chord. The adults are sessile - that is to say they are anchored to one place on the Reef. CephalochordataCephalochordates, or lancelets, are fish-like animals that have a notochord and nerve chord along the entire length of their bodies and which persist all their lives. * A notochord is a an elongated cellular chord enclosed in a sheath, that forms the primitive skeleton of chordate embryos (including humans) and adult cephalochordates.
