Turbinate: lower, middle and upper, anatomy and pictures

The structure of the turbinates

To diagnose you must know how the structure of the nose communicate with the surrounding space. The anatomy of the structure of the nasal cavities helps professionals to assess the degree of severity of the disease.

Turbinate adjacent to the lateral wall. Between them is free space, which is called a bow stroke.

Upper turbinate

The upper turbinate is part of a trellised labyrinth. Nasal plate in adults and children have the same structure. They consist of bone framework that is covered with mucous membrane. Mucus prevents inflammatory processes that can occur in the nasal cavity.

In this body there are:

  • cells with cilia, which protect the mucous membranes of the nasopharynx by pathogenic microorganisms.
  • goblet cells produce the mucus necessary to keep the purification from harmful components.

Bottom shell

The inferior turbinate resemble curved plates of small size.

They are separate bones and are located near the sky. The lower end of this body free. Beneath it is a lower nostril, which has DEEPTONE structure.

The lower part of the ethmoid bone is considered the largest site in the anatomy of the nose.

She is responsible for the proper distribution of the air flow.

The cells filter incoming air from various contaminants.

Mucous acts as the first line of defense that protects the nasopharynx by pathogenic microorganisms. In this place there are a large number of immune cells.

When infected the person begins the inflammatory process. In this way the body tries to cope with harmful bacteria. In mucous covering the bottom plate are blood vessels that can dilate in response to various factors.

Contact allergens may cause nasal congestion. A negative reaction may be caused by the changing temperature of the air entering the nasal passages.

In contrast to adult patients nasal passages in children too narrow. They have not yet formed bone tissue. Bottom shell can drop to the bottom of the nasal cavity. This defect leads to disruption of breathing.

How does the middle turbinate

The main purpose of this body is the flow of the air entering the nose during inhalation. The middle turbinate is composed of 2 parts.

Due to the curved plate overlapping the olfactory cleft. In this way it protects the receptors from contaminants. The average sink is adjacent to the apophysis of the frontal bone and the palate.

The unique structure of the turbinates is used to transmit the incoming of oxygen in the nasopharynx. In the lateral wall you can see a special bending that contributes to the development of rhinitis.

In front of the sink can be doubled to an end. To evaluate its state when performing rhinoscopy.

Functions of the nasal cavities

The shell of the nose represent a pair of dice that are designed to ensure proper breathing. When exhalation occurs the rise of the middle nasal plate.

Thanks to this mechanism closes the passage to the olfactory receptors. This is to prevent the admission of harmful impurities in the exhaust air to the nasopharynx.

Mucus necessary to capture microscopic dust particles, which is present in the air. In the process of oscillations of the cilia is the removal of mucus along with harmful bacteria and dust.

Turbinate vertical plates located on both sides. The air inhaled passes through the nasal passages. They are between shells. In the lower bone has a special opening that connects with the lacrimal channels. In this place accumulates their contents.

Such a structure of the plates serves to increase the area of the nasal cavity. It helps your body faster to warm the incoming air. In bone tissues of the nasal plates are located cavernous body.

In case of delay in blood, a person swell of the bottom shell. This increases the resistance to air flow, which can lead to the complete overlap of the nasal passages. For blood filling the cavernous bodies is affected by several factors:

  • the amount of dust in the air;
  • the development of inflammatory processes in the sinuses;
  • the temperature of the air.

The top of the bow is on the back and has openings that lead directly into the sinuses. To ensure the protection of the sinuses would be impossible without the mucosa. She is directly involved in the process of hydration of the nasopharynx.

The secreted mucus has antibacterial properties. It destroys pathogenic microorganisms. The nasal cavity performs the function of the resonator. Their status depends on the timbre of the human voice.

The inner part of the nose contains a layer of epithelium containing receptor cells. Through these cells a person can recognize different odors.

Which of the nasal conchae is a separate bone? For this you need to understand the anatomy of the nasal cavities. Thanks to the visual representation of this body in the photo you can understand that only the bottom shell may be a complete bone.

Conclusion

Nasal cavity specialists divided into 3 basins: upper, middle and lower. Knowledge of anatomy helps doctors make a correct diagnosis. Only the inferior nasal Concha is considered a separate bone.

Between them is the inhaled air, which is cleaned of various impurities. Top plates covered by a layer of epithelium, which protects the nasal passages from viruses and bacteria.
