Recently, a beautiful diagram of the structure of the tooth can be found in virtually every dentist's office.On a colorful picture painted a complex multi-layer structure, and small figures marked the different parts of the body.However, not everyone is able to immediately repeat all levels of the tooth and their functional features.This article is for those who do not know and those who do not remember very well the structure of human tooth.To supplement the presentation of the overall presentation of information about the oral cavity as a whole.
So, what is the structure of a person's mouth?Of course, first of all, when considering this anatomical region should describe the lips.They are unusual in that the skin is red border is actually not quite the skin, and has a lot of similarities with the mucosa.Itself it can not moisturize, so from time to time to lick his lips necessarily and naturally.Otherwise cracked.There is also a not very well-known fact about the cheeks - because with them it is possible to remove samples bestravmatichno cells, it takes pieces of cheek mucosa to determine the chromosomal gender athletes.Sometimes the results are surprising.
In the inner part of the cheek located small mucous glands.They secrete a protein secretion.Language consists of striated muscle, it arranged organs of taste sensations - 3 types of papillae.At the root of the tongue is a special education - lingual tonsil.This is the body immune system, and it is important in fighting infections.Structure of the human oral cavity deep rationally.
teeth are located on the gums in two rows (OK), the upper arc of a little more the bottom, so the upper teeth with the right bite slightly overlapping the lower.Now we tell about the structure of human tooth.A large part of the tooth is formed by a special type of connective tissue, full of lime - dentin.The protruding part of the tooth above the gum coated with a special solid epithelial tissue, which is called the enamel.The portion of the tooth that is hidden, covered with another type of tissue, called cement.
place where joined surface (crown) and hidden (root) of the tooth, called the neck.The line, which are connected by the enamel and cement, is named after the neck line.
Each tooth contains a cavity inside, called the pulp.Wide range of top of the tooth pulp chamber is named, and the area at the root - root canal.It is this area dentists say when told about the obturation.The content of this field - pulp - has a lot of nerve fibers and blood vessels.It is this area provides the vital functions of the tooth.The pulp is surrounded by a layer of special cells - odontoblasts.They specialize in the development of dentin.They are like the cells that form human bone.The structure of human tooth resembles in many ways the bone structure.
vessels and nerves that take care of the tooth included in it through the lower apical foramen, which is located at the top of the root of each tooth.
As teeth are attached to the bone?With special fibers, which consists of connective tissue.These bundles are called the periodontal ligament or a periodontal.They consist of collagen fibers, one end they are immersed in the extracellular matrix of bone alveolus (special recesses in the gum to tooth), and on the other hand - to the tooth dentin.
When the process of tooth eruption, gum is fixed with respect to the enamel, and cervical line does not protrude outward.But the elderly gums "retreats" and becomes visible to the dentin.Of course, this makes human teeth in a respectable age more vulnerable.
human tooth structure is not too difficult, but the damage is dangerous at any level.Therefore, we must comply with all hygiene measures, and just brushing your teeth is not enough, we still have a special floss to clean the spaces between them.
