Question

The vertebral coloum is not made of one bone why

Answer 1

Vertebral columns. The series of vertebraethat extend from the cranium to the coccyx, and serves as a flexible bony case for the spinal cord. A single bone is unable bend therefore vertebral column not made of a single bone . bcoz if it is made up of singlebone then we cant move our body.

The structural composition of back bone allows us to bend, crouch, stand and lie down on the ground. The vertebral units promote this movement. If back bone is made up of one long bone then we would never be able to sit, crouch or lie. One single bone means no flexibility in the structure of a bone.
