NASAL EPITHELIUM Meaning and
Definition
-
Nasal epithelium refers to the specialized tissue lining the nasal cavities. It is a thin layer of cells that covers the interior of the nose, helping to protect and facilitate the function of the respiratory system.
The nasal epithelium is made up of various types of cells, including ciliated epithelial cells, goblet cells, and basal cells. Ciliated epithelial cells are responsible for the movement of mucus and foreign particles out of the nasal passages, aiding in the removal of dust, allergens, and other potentially harmful substances from the air we breathe. Goblet cells produce mucus, which acts as a protective barrier, trapping particles and preventing them from entering further into the respiratory system. Basal cells are responsible for the continuous regeneration and repair of the epithelial tissue.
In addition to its role in filtering and protecting the respiratory system, the nasal epithelium is also involved in the sense of smell. It contains specialized nerve cells known as olfactory receptor cells, which detect and transmit chemical signals from odorous substances to the brain, allowing us to perceive smells.
Overall, the nasal epithelium plays a vital role in maintaining the health and proper functioning of the respiratory system and contributes to our ability to smell and perceive odors.

Etymology of NASAL EPITHELIUM
The word "nasal" originates from the Latin word "nasus", which means "nose". It refers to anything related to the nose. The word "epithelium" comes from the Greek word "epithelioma", meaning "growing upon" or "epi" (upon) and "thelē" (nipple). In anatomy, "epithelium" refers to the thin tissue layer that covers internal and external surfaces of the body. Thus, the term "nasal epithelium" is used to describe the specific tissue lining the inside of the nasal cavity.
