The nasal mucosa lines the nasal cavity. ... In the olfactory region the mucous membrane is yellowish in color and the epithelial cells are columnar and non-ciliated; ...
In general, nasal mucus is clear and thin, serving to filter air during inhalation. During times of infection, mucus can change color to yellow or green either as a result of trapped bacteria [24] or due to the body's reaction to viral infection. For example, Staphylococcus aureus infection may turn the mucus yellow. [25]
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.
This segment is located in and beneath the mucosa of the roof of each nasal cavity and the medial side of each middle turbinate. Histological sections appear yellowish-brown due to the presence of lipofuscin pigments. Olfactory mucosal cell types include bipolar neurons, supporting (sustentacular) cells, basal cells, and Bowman's glands.
Its color can vary from transparent to pale or dark yellow and green, from light to dark brown, and even to dark grey depending on the contents. [1] The body naturally produces about 1 quart (about 1 litre) of phlegm every day to capture and clear substances in the air and bacteria from the nose and throat .
The peripheral olfactory system consists mainly of the nostrils, ethmoid bone, nasal cavity, and the olfactory epithelium (layers of thin tissue covered in mucus that line the nasal cavity). The primary components of the layers of epithelial tissue are the mucous membranes , olfactory glands , olfactory neurons , and nerve fibers of the ...

The olfactory mucosa is the neuroepithelial mucosa [1] lining the roof and upper parts of the septum and lateral wall of the nasal cavity [1] [2] which contains bipolar neurons of the primary receptor neurons of the olfactory pathway, as well as supporting cells.
