Why is cartilage important in the human body? AS SUMMARY

The cartilage is a type of dense connective tissue.
It consists of collagen fibers and / or elastin fibres, and the so-called chondrocytes, all of a company gel earth as a substance called the matrix.
The cartilage is avasculaire (no blood vessels) and nutrients are distributed through the matrix. Cartilagine different functions, particularly by providing a framework in which deposits of bones and can be equipped with smooth surfaces available to monitor the movement of articulation of the bones.
The cartilage in many places in the body, including seals assembly, chest, ear, nose, bronchial tubes and spine.
There are essentially three types of cartilage: hyaline, elastic and fibrocartilage. There are three different types of cartilage, each with specific characteristics according to their function. Hyaline cartilage Hyaline cartilage is the richest type of cartilage.
Hyaline The name derives from the Greek word hyalos, glass effect. And 'the matrix or translucent material basic research. E 'avasculaire hyaline cartilage, primarily of type II collagen. Hyaline cartilage lining of the bones is located in the joints (or the articular cartilage, as a rule, Gristle) and is also inside the bones, as a center of ossification, or the growth of bones. In addition hyaline cartilage from most forms of embryonic skeleton.

Cartilagine articular cartilage is a specialization of hyaline cartilage left at the end of long bones and not perichondrium. Cartilagine elastic Cartilagine elastic (also known as yellow cartilage) is located in the auricle of the tubes and varied as the walls of hearing loss (eustachian) tubes and larynx, and particularly in the epiglottis. The cartilage is to open the tubes. Cartilagine elastic is similar hyaline cartilage elastic, but contains packages (elastin), in the matrix. This follows a rigid structure, which is still elastic.

Cartilagine fibrous Fibrose cartilage (also known as cartilage and white) is a special type of cartilage in the difficult support, or a great force, such as the vertebral column, the public and other symphyses, and on the page or the connection tendons, ligaments to the bone. Rarely is clear dividing line between the neighbours and fibrocartilage hyaline cartilage and connective tissue. The fibrocartilage found in the spinal column contains more collagen hyaline. In addition to type II collagen found in hyaline cartilage and elastic, fibrocartilage contains collagen type I, not on the form fibrés light under the microscope.

Fibrose cartilage seems to be missing, a perichondrium, because it can not be because of collagen type I. If hyaline cartilage at the end of long bones like the femur is damaged, is often replaced by fibrocartilage not reduce the weight of forces and
