Intervertebral Discs Essay

Intervertebral discs are the rubbery pads that fill the space between the bones of the spine, known as vertebrae. They act as shock absorbers for the spine, making the spine more flexible than it would be without the discs. The discs separate the vertebrae and keep them from rubbing together and causing damage to the bones but unfortunately, the discs themselves can suffer injury and cause a multitude of problem and significant pain.
When a there is an injury or a large amount of stress is put on the spine, the inner material of the intervertebral discs may swell, pushing through its tough outer membrane. This can cause the entire disc to become distorted or bulge in spots. Sometimes, all or part of the inside material of the disc may protrude through the outer casing at a weak spot and put pressure on surrounding nerves. If further activity or injury causes the membrane to rupture or tear, the disc material may protrude (herniate) further resulting in …show more content…
One of the most common disc disorders is known as degenerative disc disease. As a natural result of aging, the intervertebral discs change in composition and size. By adulthood the blood supply to the disc ceases and the soft inner material of the disc begin to harden making the disc less elastic. As time passes, the discs become tougher until they are the consistency of hard rubber. This process makes the outer protective lining of the discs weaker and more prone to injury. There is then a gradual loss of flexibility and the ability of the spine to compensate for extra pressure or injury. Degenerative disc disease can be far more serious in some than in others. Severe cases typically result from a deficiency in collagen, the material that makes up cartilage. It can be aggravated by poor muscle tone, poor posture, and even obesity all which put excessive strain on the spine and the ligaments that hold the discs in
