Cartilage is a type of dense connective tissue, characterized by this tissue as harsh and flexible as well. Cartilage contains cartilaginous cells, which are divided into two parts:
1. Young cartilage cells: located in the circumference of the cartilage, base, ovoid nuclei.
2. Mature cartilage cells: They are circular cells. It has a nucleus or two nuclei.
The cartilage itself is a type of cartilage, from which the cartilage is flexible, from which the cartilage is hyaline, and the cartilage of the fibrous cartilage is found in many parts of the body. It is found in the rib cage, in the ear and nose and in the articular surface of the bones. And popular pipes.
What distinguishes cartilage is that it does not contain blood vessels. It is fed by proliferation and cartilage is slower than other connective tissues. The cartilage contains fiber, such as fiber-producing fibers, and flexible ones. It also contains the essential substance consisting of cartilaginous mucous protein, with water, in addition to sodium salts.
There are three types of cartilage in the human body:
1. The cartilage, which is called a vitreous glass, is blue, surrounded by a vascular membrane. This type of cartilage consists of a fibrous layer and a layer of cartilage cells. This cartilage is found in the trachea, the bronchi, and in the joints of the moving bone, and is also found in the nose.
2. The flexible fibrous cartilage, we find this cartilage in the ear flank in the body, and found in the audio channel, and in the channel Ostaki.
3. White fibrous cartilage: We find this type of cartilage in the articular discs between the vertebrae, and we find it in the shear bone, and in the collarbone, and we also find in some cartilages of the bones of the pelvis in the human body.
Function of cartilage in the body:
1. One of the most important functions of cartilage in the body: to keep the airways open.
2. Cartilage also helps in the formation of the skeleton in the human body.
3. The cartilage forms smooth surfaces, to help and facilitate joint movement.
