Your backbone protects your spinal chord, which allows for most of the exchange of information from the nervous system to the brain or vice versa. If you did not have a backbone, your spinal chord would be easily damaged which, if damaged in the right spot, could cause full-body paralysis.
Its front is made up of cartilages and back part is ethmoid bone
No. Reptiles are vertebrates, and therefore have a spinal column made of bone.
Letters.
No, they have a shell made out of calcium carbonate.
Mammals are vertebrates and like all vertebrates have only one back bone . Back bone is made up of vertebrae .
It would make sense...
Sometimes they were made with bone(if that was all they could find)
Even though a lamprey is a slimy little animal they do indeed have a back bone of this back bone unlike most is made of mainly just cartilage.
Because it is made up of a series of bones called vertebrae and is not one continuous bone. The longest bone, at a guess, is probably the femur.
A single, long bone would be rigid, to make a spine that will bend it has to be made of smaller articulated units.
