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.
How many curvature does vertebral column have?
You have the convex anteriorly curve of cervical vertebrae. You have the concave anteriorly curve of thoracic vertebrae. Again you have the convex anteriorly curve of lumber vertebrae. The sacrum goes steep backward from the last lumber vertebra. Here no curve is described probably. So you have lardosis of cervical and lumber vertebrae. You have kyphosis of the thoracic vertebrae.
How many vertebra do human have?
Almost all humans are born with 33 separate vertebrae. By adulthood, most have only 24. This is due to the fusion of the vertebrae in certain parts of the spine during normal development. Different textbooks give different answers to this question. The confusion comes from the fact that the two lowest vertebrae -- the sacrum and the coccyx -- are each one bone, but they are made up from smaller bones fused together. There are 24 separate vertebrae; then there is the sacrum, which is formed from 5 fused vertebrae; and finally the coccyx, which is formed from between 3-5 fused vertebrae. Therefore, if the coccyx and sacrum are each classed as one vertebra, then there are 26 vertebrae. If the fused vertebrae are all counted separately, then there are 32-34 vertebrae.

What are the 26 small backbones?
Typically there are 7 vertebrae in the neck called cervical vertebrae. They are commonly called C1-C7. The first cervical vertebra is also called the atlas, and the second, the axis. Typically there are twelve thoracic vertebrae to which the ribs attach. Typically there are five lumbar vertebrae in the lower back. Caudal ('toward the tail' or below in the standing position) to the lumbar vertebrae is the sacrum. Caudal the the sacrum is the coccyx. It is often called the tailbone. Commonly, the coccyx is formed by two or three segments. Many people have a sixth lumbar vertebra which is usually a part of the sacrum which did not fuse to the other segments of the sacrum during development. Sometimes a vertebra, usually a thoracic vertebra, fully develops on only one side, so one might say there are 12 vertebrae on one side, and 11 on the other. That is called a hemivertebra. Sometimes 2 vertebrae are fused together, making one bone instead of two.
