Articular Disc

Articular disc: what is it and how does it work?

The articular disc, also known as discus articularis, is an important part of the joints in our body. It is located between the bones of the joint and serves as a shock absorber that absorbs shock and protects the bones from damage.

An articular disc is made up of two parts: an outer fibrous shell and an inner soft tissue called the nucleus. The fibrous membrane consists of collagen fibers that form a ring around the nucleus. The core consists of a gelatin-like mass that contains water and proteoglycans.

The articular disc has two main functions. First, it serves as a shock absorber, which absorbs shock and protects bones from damage when moving. Secondly, it also allows the bones of the joint to move freely relative to each other.

However, like any other part of the body, the articular disc can be subject to various diseases and injuries. One of the common diseases is disc protrusion, when the nucleus protrudes beyond the fibrous membrane. This can lead to compression of the nerve endings and joint pain.

Also, the articular disc can be damaged by injury or overuse, which can lead to rupture of the fibrous membrane and prolapse of the nucleus.

To prevent diseases and injuries of the articular disc, it is necessary to monitor your health and correctly distribute the load on the joints. Regular exercise and a healthy diet will also help keep your joints healthy.

In conclusion, the articular disc is an important part of our body that performs several important functions. It allows the bones of the joint to move freely relative to each other and also acts as a shock absorber that absorbs shock and protects the bones from damage. Therefore, it is necessary to take care of your joints and monitor their health.
