Many common terms related to neck pain and lower back pain are slipped discs, herniated disc, disc disease and degenerated disc. Why do these conditions take place? What are the main reasons? What can you do to prevent it or treat it? Let us discuss these questions and find the answers to them. It is important to know about it.
Let us get some facts understood first. The vertebrae consist of 24 bones and makes up the spinal column. These are aligned vertically and are known as facet joints. These are located parallel to the direction of the spine. The other joints are located at the bottom and at the top of the vertebrae. They are weight bearing in function and are horizontal joints. Except for the two top vertebrae in the neck, there is an intervertebral disc between each pair of the vertebrae. They keep on getting smaller as we travel upwards in the spine. Their shape also changes as they move up and this is because of the change in the shape of the bones.
The annulus is wrapped in layers around the nucleus to contain its pressure. These layers are somewhat like the layers of an onion. The fibers of one layer are at right angles to the next layer. These layers have to be tough and non-yielding; otherwise the soft nucleus would lose its shape and spill all over the place. In fact this is indeed what does happen if the annulus breaks down. This incident is known variously as a slipped disc, a herniated disc, a disc protrusion, or a disc bulge. These terms often depend on the degree of nuclear movement, which depend on the degree that the annular cartilage breaks down.
There is a part called annulus and it is located around the nucleus so that it can contain its pressure. It is just like the layers of an onion. The fibers of one layer are located at right angles to those of the other layer.
