You probably know that you have cartilage in your ears and nose, and the shark’s skeleton is almost entirely made of cartilage. But it is not all information about elastic, and at the same time, strong connective tissue, which is not only in the ears and nose.
Not all cartilages are equal.
Crystallography Cartilage is found in the airways and ear canal, and is the most common type of cartilage in the human body. It also has a high concentration of collagen, which allows it to shape parts of the body while providing some elasticity. It is smooth and allows bones in the joints to move during movement. This type of cartilage is found at the ends of the ribs, on the surfaces of bones in the joints, as well as in the trachea and larynx. It provides cushioning in joints.
Elastic Cartilage is the most flexible of the three types. Elastin fibers provide this type of cartilage with the ability to return after a stretch, making it ideal for places where it is in the body: the outer ear (it may be folded, folded, it still has its own Will return to normal size) and epiglottis (cartilage allows you to swallow) without choking on food, as well as breathing).
Fibrous Cartilage is a strong and dense type of cartilage that occurs in the meniscus in the knee joint, as well as between the vertebrae and the tempomandibular joint, where the jaw connects to the skull. The fibers of such cartilage are very dense, and by nature this form is the most durable of all types of cartilage.
- In childhood, cartilage can predetermine your future development.
The relationship between cartilage and bone growth rate can determine how tall you will be as you grow. If the cartilage located near the ends of the bones grows faster than the bone, the person will grow much taller when they are adults. If bone growth in adolescence is faster than cartilage growth, the person will be less. In adults, cartilage development is already very minor.
- There is no direct blood supply to the cartilage
With age, the cartilage in the body is restored much more slowly than other cells, because it is devoid of blood vessels, meaning that it does not have a direct blood supply. That is why after 40 years, cartilage injury becomes a very serious problem for runners due to arthritis.
After damage to cartilage, its elastic fibers are not restored, as do skin cells. Therefore, for people over 40 years of age with cartilage damage or arthritic knees, it is not recommended to exercise with a high weight.
- Cartilage has no nerve
There is no nerve in the cartilage that produces sensation. When patients lose their cartilage, the pain they experience comes from a bone that is not protected by cartilage. Eventually, cartilage can reduce friction 1000 times better than two pieces of ice rubbing against each other.
- Cartilage cannot be restored
Since cartilage is not restored and grows primarily only in childhood, the wear of cartilage acquired in childhood will be felt in adulthood.
At the same time, due to the fact that blood vessels do not have access to cartilage, it is possible to restore lost cartilage with transplantation from donors, without the need for immunosuppression drugs that suppress immunity.
- Cartilage deteriorates over time
For most youth, cartilage is 85% water, and for the elderly the figure is 70%. But the decline is not irreparable.
One of the non-surgical options to improve the condition of joints and cartilage is to take glucosamine + chondroitin sulfate. It is clinically proven that it stimulates cartilage restoration and improves joint mobility.
