lõhnaepiteel

Lõhnaepiteel is a type of epithelial tissue found in the respiratory system, specifically in the nasal cavity and the trachea. Its primary function is to produce and secrete mucus, which plays a crucial role in protecting the respiratory tract from inhaled particles, irritants, and microorganisms. The mucus produced by lõhnaepiteel is thin and watery, facilitating the clearance of foreign substances through coughing and sneezing.

The tissue is named after the German anatomist Johann Friedrich Lõhne (1760-1811), who first described it in detail. Lõhnaepiteel is characterized by its pseudostratified columnar ciliated cells, which are responsible for the movement of mucus towards the oropharynx. These cells are supported by a layer of non-ciliated cells that secrete the mucus.

In addition to its protective role, lõhnaepiteel also contributes to the sense of smell. The olfactory receptors, which detect odorant molecules, are located in the non-ciliated cells of the nasal epithelium. The cilia in the pseudostratified columnar cells help to keep the nasal cavity clear by moving mucus away from the olfactory receptors.

Lõhnaepiteel is a vital component of the respiratory system, ensuring the health and functionality of the nasal cavity and trachea. Any disruption or damage to this tissue can lead to respiratory infections, inflammation, and other related health issues.
