Nasal Cavity

The Nasal Cavity is a space occupying a central position in the facial skull, opening anteriorly with a pyriform aperture bounded by the nasal notches of the upper jaws and the anterior edge of the nasal bones. At its lower edge protrudes the anterior nasal spine, which continues posteriorly into the bony nasal septum, which divides the nasal cavity into two halves. Through paired choanae, separated from one another by the posterior edge and wings of the vomer, the nasal cavity communicates with the pharyngeal cavity, and through the nostrils with the external environment.

The nasal cavity is a space located in the center of the facial skull and occupies a central position between the orbits of the eyes. It opens anteriorly through a pyriform aperture bounded by the nasal notches of the maxilla and the anterior margin of the nasal bone. At the lower edge of the nasal cavity, the anterior nasal spine protrudes, which continues posteriorly and enters the nasal septum. This septum divides the cavity into two halves, each of which communicates with the external environment through the nostrils and paired choanae.

Through the choanae the nasal cavity is connected to the pharyngeal cavity. The anterior nasal spine is an important landmark when performing nasal surgery, as it can be used to determine the position of the nasal septum. In addition, the nasal cavity has many other structures such as conchae, turbinates and nasal openings, which play an important role in the function of breathing, smell and hearing.

Thus, the nasal cavity is the central element of the facial skull, which performs various functions related to breathing, smell and hearing. It is also home to many important structures that can be used to diagnose and treat various diseases.

The nasal cavity is the middle ear of the external ear system. The main function of the nasal cavity is to humidify the inhaled air or moisten it in case of dryness. This reduces eye irritation and reduces drying of the mucous membranes of the upper respiratory tract, especially the nose. However, not all of the body's moisture is lost in the nasal cavity. The air is purified by the hairs of the nasal mucosa and the villi of the tongue, which remove dust and allergens that enter the respiratory tract. As a rule, this process is accompanied by partial recovery of water.

The nasal cavity is one of the most important organs of the human body. It is located in the middle of the face and occupies a central position. The cavity is a space open anteriorly towards the pyriform opening, bounded by the nasal recesses of the maxillary bones and the anterior part of the nasal skeletons. Because of its shape, it allows us to smell odors and hold water around the nasal cavity to humidify the air before it reaches the lungs.

At the lower edge of the nasal cavity is the anterior nasal bone, which continues upward and posteriorly to form the bony septum. The bony septum divides the cavity into two parts, each of which opens into a separate passage - the paired choana, located on the back of the right and left halves of the cavity. The joana opens into the oral cavity through the pharyngeal cavity and connects to the external part through the nasal passages.

It turned out that the nasal cavity plays an important role in our health. In this part of our body, millions of bacteria and viruses move along the back of the nose, and we are exposed to a huge number of germs throughout our lives. Although these microorganisms are home to more than 90% of all known bacteria, they do not harm our bodies if their levels are low enough. In order for it to remain the same, it is very important to properly maintain the nasal cavity. For example, poor hygiene or poor habits such as smoking should be avoided.
