It is part of the respiratory mucosa, the mucous membrane lining the respiratory tract. [1] [2] The nasal mucosa is intimately adherent to the periosteum or perichondrium of the nasal conchae. It is continuous with the skin through the nostrils, and with the mucous membrane of the nasal part of the pharynx through the choanae.
The nasal mucosa lining the nasal cavity and the paranasal sinuses carries out the necessary conditioning of inhaled air by warming and moistening it. Nasal conchae, shell-like bones in the walls of the cavities, play a major part in this process. Filtering of the air by nasal hair in the nostrils prevents large particles from entering the lungs.
Nasal mucus may be removed by blowing the nose or by using nasal irrigation. Excess nasal mucus, as with a cold or allergies, due to vascular engorgement associated with vasodilation and increased capillary permeability caused by histamines, [14] may be treated cautiously with decongestant medications. Thickening of mucus as a "rebound" effect ...
Post-nasal drip (PND), also known as upper airway cough syndrome (UACS), occurs when excessive mucus is produced by the nasal mucosa. The excess mucus accumulates in the back of the nose , and eventually in the throat once it drips down the back of the throat.

Medical measures include: Nasal irrigation using normal saline [4] Nasal irrigation and removal of crusts using alkaline nasal solutions. 25% glucose in glycerine can be applied to the nasal mucosa to inhibit the growth of proteolytic organisms which produce foul smell.
Nasal mucosa has a rich blood supply and has venous sinusoids or "lakes" surrounded by smooth muscle fibers. These smooth muscle fibers act as sphincters and control the filling and emptying of sinusoids. Sympathetic stimulation causes vasoconstriction and shrinkage of mucosa, which leads to decongestion of the nose.
The olfactory epithelium is a specialized epithelial tissue inside the nasal cavity that is involved in smell. In humans, it measures 5 cm 2 (0.78 sq in) [1] and lies on the roof of the nasal cavity about 7 cm (2.8 in) above and behind the nostrils. [2] The olfactory epithelium is the part of the olfactory system directly responsible for ...
(D) NALT located on the nasal septum. NALT in mice is localized on cartilaginous soft palate of upper jaw, it is situated bilaterally on the posterior side of the palate. It consists mainly of lymphocytes , T cell and B cell enriched zones, follicle-associated epithelium (FAE) with epithelial M cells and some erythrocytes .
