Explanation In intervertebral discs, there is a blood supply till the age of eight years and after that the discs will become avascular. Aging can cause changes in the posture and position of the body that lead to the changes in the pressure of the internal discs. It results in pumping action in the disc. Injury and aging will also affect the water-absorbing capacity of the discs. This occurs when there is a decrease in shock-absorbing capability of discs. Due to aging, the fluid content of all the discs will be reduced by 35% (approx.). The loss of water in the intervertebral discs is due to the alterations in the normal regenerative process...

Summary Introduction

To explain: The consequences of loss in intervertebral disc hydration that accompanies the aging process.

Concept introduction: The intervertebral discs are articulations between the symphysis joints. The two main functional structures in the intervertebral disc are annulus fibrosus and nucleus pulposus. Annulus fibrosus are fibrous, thick cartilaginous ring that forms the external layer. Nucleus pulposus is a gelation like substance that contains higher fluid content and located present inside the annulus fibrosus.
