The intervertebral disc (IVD) is the fibrocartilaginous joint located between each vertebral body that confers flexibility and weight bearing capabilities to the spine. The IVD plays an important role in absorbing shock and stress applied to the spine. which helps to protect not only the vertebral bones. but also the brain and the rest of the central nervous system. https://www.roneverhart.com/ESP-LTD-SD-2-Sammy-Duet-Signature-Model-Electric-Guitar-Black-p20045/
