Answer 1

Answer:

If we had just one long bone, we wouldn't be able to bend easily. Our backbone is made up of 33 small bones called vertebrae. Since it is made up of a chain of bones, it is flexible.

Answer 2

Key parts of your spine include vertebrae (bones), disks, nerves and the spinal cord. The spine supports your body and helps you walk, twist and move. The disks that cushion vertebrae may compress with age or injury, leading to a herniated disk. Exercises can strengthen the core muscles that support the spine and prevent back injuries and back pain.
