Sinuses: anatomy, structure and function in adults and children

What are the sinuses?

Not everyone knows that in the structure of the facial part of the skull are hollow areas, which are called the sinuses. The final formation of this part is to 5 years. Sinuses are connected by a special passage with the inner cavity of the nose.

Paranasal sinuses, have different shapes and sizes. They can change during various diseases. Inflammation is each person differently, based on individual physiological characteristics.

The structure of the nose

Clinical anatomy of the nose is quite complex. With regard to its outer region, it includes the back, wings, middle part and base. If you look inside (from the mouth), the eyes rest on the sky that is the limit of its interior.

It is divided into 2 halves by partitions that form the two nostrils. In addition to these barriers, there are also other sides:

  1. Lower.
  2. Top.
  3. Back.
  4. Lateral.

The nasal cavity consists of cartilages, membranes and bone. All they are the most mobile, as everyone can make it on their own. There are also 3 sinks:

  1. Lower.
  2. Average.
  3. Top.

These sinks are connected with the moves:

  • The top is in the back.
  • The middle holes of this course have access to the frontal and frontal sinuses.
  • The bottom is a tear duct.

As for the septum that divides the nose in half, it is almost all slightly shifted to one side. This is the reason of asymmetry of the nasal passages.

What are the functions of the nose?

On the whole nasal cavity has a large number of functions. Experts believe that proper breathing depends on the work of the whole organism. In particular, such functions as:

  • olfactory;
  • resonator;
  • protective;
  • respiratory.

The latter provides oxygen to the whole body, including tissues and cells that is necessary for a stable life. The protective function is working on cleaning the incoming air and its subsequent decontamination. Olfactory function handles the odors. The resonator function is responsible for the voice, making it unique.

To ensure your health, it is necessary to periodically x-ray of the nose.

Anatomy and function of the sinuses

Proper anatomy of the nose plays an important role in human health. The internal divisions are also included and all sinus. Anatomy of sinuses no less complex and important than its function, so you should consider this issue in more detail.

The main sinuses are referred to as wedge-shaped. This name they received due to the location of the sphenoid bone. Due to the fact that they border with other equally important parts of the body (pituitary gland, carotid arteries, optic nerves), inflammation is very dangerous.

The maxillary sinus is the largest of all. They are located in the upper jaw. Each person they are different sizes. Each has the recesses. The structure of the sinuses in its form resembles a pyramid with three faces.

The inflammatory process in the maxillary sinuses are formed in the anastomosis. Due to the fact that their lower part is bordered by the roots of the teeth of the upper jaw, are very often any serious dental disease can lead to inflammation.

The frontal sinuses are in the forehead above the eyebrows. They connect with the nasal cavity through a fistula. Some people have additional partitions. Interestingly, frontal (forehead) sinuses are not all the people, and about 95%. Full size, they reach only to the time of puberty.

The number of such cells reaches 15. Functions of the sinuses are completely consistent with the basic functions of the nose.


Despite the fact that the entire olfactory system has a rather complex structure, they are versatile and easily brought back to normal with almost any disease, if you have time to bethink and to start treatment.

If in time not to be taken for the treatment of diseases, the functioning of this system can be disrupted, which would entail the problems associated with other body functions. Therefore, it is necessary to take measures in time, together with a specialist.
