Back Bone 

1.    Why is backbone important?

The vertebral column or back bone, as it is commonly known as, is the main strong structure of the back.

Just like in a tall building, the columns are the main structure giving stability to the building – The vertebral column gives stability to the back along with flexibility too.

2.    What is the composition of the back?

A back has the vertebral column made of multiple vertebral bodies and intervertebral disc and other structures such as muscles, ligaments.

     3. How many bones are there in the vertebral column?

There are

1.	Neck – cervical spine	7
2.	Chest-Thoracic spine	12
3.	Abdomen-Lumbar spine	05
4.	Pelvis –Sacrum	05
5.	Coccyx	04

4.  What is tail bone?

The terminal part of the vertebral column is call coccyx or the Tail bone.With the evolution, human being does not have tail but the terminal shrunken portion of group of bones is called as Tail – bone.

5.  What is the architectural design of the vertebral column?

The vertebral column in the human beings has a unique design from the front like the building column as it is straight.

But when seen from the side, there are curvatures just like the  Alphabet ‘S’.

In the neck region, the curvature is having convexity  (or anterior bend )towards the front side . In the chest curvature is the opposite i.e. at behind, same the curvature is in from in stomach region.

Knowledge of this curvature is important in postural backache.

Normal standing posture stand erect shoulder braced behind chest forward, tummy tucked in, shoulder & hip in same straight line, feet spread apart 12-15 inches.In this position can stand comfortably for a long time, the natural curvature of the spine is preserved.

So, there is least strain on the structures of the vertebral column.
