What is Spine?
Spine is made up of alternate stack of vertebrae (rectangular bones) and discs (soft cushion like structures which act as shock absorbers) in front and has a bony tunnel (Spinal canal) on back which allows the spinal cord and nerves to pass through it. It extends all the way from the head to tail bone. Spine is most important pillar of our body which helps us stand erect on our legs and protects the spinal cord and nerves.
