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 difference between typical and atypical vertebra?
one is typical, one isn't...You can connect tha dots
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.
The firm flexible rod found in the dorsal area in chordates?
Notochord.
Difference between notochord and vertebral coloum?
1) The notochord is the defining structure of the phylum Chordata, which includes all vertebrates. In its "mature" state, the notochord is a rod of large cells constrained by a thick extracellular sheath and positioned between the developing spinal cord and gut. Turgor pressure generated by notochord cells exerted against the sheath gives the notochord stiffness, imparting the mechanical properties required for one of its main functions as the central axial skeletal element of the developing embryo. 2) The notochord exists transiently during the life of most vertebrates. During its short life, however, the notochord plays another critical role for developing embryos,.producing a variety of secreted growth factors, such as Sonic hedgehog, which instruct surrounding tissues to acquire particular differentiated fates. A number of embryological experiments, for example, tell us that, without notochord-derived signals, motorneurons in the spinal cord would not form, the pancreas insulin-producing cell would not differentiate, and the body muscles would not be produced properly. Without the axial skeletal support of the notochord, many lower vertebrate larvae, such as fish fry and tadpoles, become severely shortened and cannot swim or feed properly. Thus many of the mutations affecting zebrafish notochord development are named after the seven dwarves.
What is neck vertebra?
A neck vertebra is a cervical vertebra, one of the bones of the spinal column in the neck.
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.
The notochord is a characteristic of?
The notochord is a characteristic of the 9th & 10th division of the kingdom animalia ,i.e., Protochordata and Vertebra
Do jellyfish have a notochord or vertebra?
No. They have a very simple nervous system that includes neither of these features. Hence, they are not chordates.

Identify one similarity and one difference between vertebrates and other chordates?
They both have a notochord but a chordata does not have a back bone and the vertebrate does
What does covertebral mean?
Between two vertebra.
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 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.
Is spondylolisthesis the forward movement of the body of one of the lower lumbar vertebra on the vertebra below it or on the sacrum?
Spondylolisthesis is the forward displacement of one vertebra over the one beneath it. It commonly occurs in the lower lumbar region, especially between the fifth lumbar vertebra and the first sacral vertebra (L5-S1).
The notochord of vertebrates is replaced by a nerve cord when the animal becomes an adult?
No, the notochord and the nerve cord arise from different germ layers. The notochord is replaced by an ossified backbone, though there are still remnants between the vertebrae. The nerve cord, however, is protected by the ossified vertebral column.
The region between the lungs from the breastbone to the vertebra is called the?
The Mediastinum.
What articulation between skull and first vertebra?
occipital condyle
