Cartilage: flexible and elastic fabric
What is it and main features
Cartilage, also known as cartilage tissue, is a kind of flexible, connective, and elastic tissue that humans possess in various parts of the body. It is composed of a gelatinous matrix formed mainly of proteins and carbohydrates.
Human cartilage is light gray or white.
The cartilages of the human body are not irrigated by blood as they have no blood vessels. In this way, they receive oxygen and nutrients through the diffusion process.
Due to its flexible property, it adapts to the bony connections of the body, ensuring the reduction of external impacts and friction between bones. It also serves to shape and support some parts of the body, such as the ears and nose.
- They are very resistant and strong, because they are formed by dense collagen fibers. They are present at the ends of bones, in the joints. They are also present in the nose (nasal passages), bronchi and trachea.
- It has little amount of gelatinous matrix in its composition. It is made up of high density collagen fibers and therefore withstands high pressures. We can find this kind of cartilage in the jaw and the menisci of the knees.
- Composed of large amount of elastin fibers. It is very flexible and light. It is present in the nose, larynx, ear tube and epiglottis. It has little amount of collagen.
