Answer:
Explanation:
Your spine is made up of 24 small bones (vertebrae) that are stacked on top of each other to create the spinal column. Between each vertebra is a soft, gel-like cushion called a disc that helps absorb pressure and keeps the bones from rubbing against each other.

the backbone is made up of several small bone instead of a single bone because if there was a single bone when there is a high chance of damage to the bones when we make our body straight according to the posture.
Explanation:
- There are some cusions between the vertebral bones. They absorve the pressure when we we extend the vertebra.
- In addition to this there is slight decrease in the the distance between two when we we try to extend our posture. As a result of this there are many small vertebra instead of a single long bone.
