All chordates have a supportive rod along their back called the?
notochord
At some stage of their development all chordates have a supportive rod along their back called the?
Notochord
Do frogs have a notochord?
YesIt is true that humans have notochords, however, this is true only when we are a developing embryo (we lose the this post-embryonic structure as adults). The notochord, being the stiff, supportive rod-like structure that it is, allows for us as vertebrates, to develop vertebrae. After the age of four, humans actually do have leftover PIECES of the notochord, which athletes may recognize as disks in between each vertebra within our spine.Here is a useful link!notochord
What are the charcterisics of a chordate?
At some point in their lives, a chordate will have a notochord, a nerve cord that runs down their back, and a slit in the throat area. The phylum name Chordata came from the notochord, a flexible rod that supports the back. They include fishes, amphibians, and reptiles.(I got this answer from my science textbook)Characteristic features of Chordata1. The chordates are one of the most diverse and successful of all animal groups.2. They are found in all regions of the world.3. They have a skeletal rod called Notochord, lying on the dorsal side of the body.4. There is a nerve cord that lies dorsally in the body, directly above the notochord.5. There is presence of Pharyngeal Gill slits atleast at the embryonic stage.6. Digestive system, Circulatory system and Nervous system are well developed.7. Those animals in which the notochord is replaced by a series of vertebrae are called as Vertebrates.8. Amphibia, Reptilia, Aves, and Mammalia are some of the classes of Phylum Chordata.They have bilateral symmetry, are coelomates, complete digestive system, and live in marine, terrestrial, and freshwater.All chordates have pharyngeal slits, which are openings that connect the inside of the throat to the outside of the neck, often used as gills. Their main feature, the notochord, a bundle of nerve fibers which connect the brain with the muscles and organs is present in all chordae's as well.In chordates, four common features appear at some point during development: a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail.
The three things all chordates have?
Chordates all possess a notochord (dorsal supporting rod), gill slits, and a dorsal nerve cord some time in their life cycles.
Which phyla possesses members that have a notochord?
Chordata is the phylum that possesses members with a notochord, which is a flexible rod-like structure that provides support. This phylum includes animals such as mammals, birds, reptiles, amphibians, and fish.
All chordates have a supportive rod along their back called the?
notochord
In chordates the long supporting rod that runs through the body is called?
it is called a notochord.
The firm flexible rod found in the dorsal area in chordates?
Notochord.
At some stage of their development all chordates have a supportive rod along their back called the?
Notochord
What is the definition of notochord?
Notochord- a flexible rod that supports a chordates back.notochord is a stuff rod of conective tissue.it is present in the mid_dorsal region of the embryo.in the lower chordates .the notochord is present throughout of life but in vertebrates .the vertebral column or bacjbone replaces it.
What is the phylum of penguins?
Penguins belong to the phylum Chordata, which includes animals with a notochord (a flexible rod-like structure) at some stage of their development.
What is a stiff rod of tissue that gives rise to the spine?
notochord
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.
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.
Flexible rod that supports an animal's back?
I believe it's a spine or backbone.
