MEATUS NASI Meaning and
Definition
-
Meatus nasi, also known as the nasal meatus, is a term used in anatomy to refer to the three spaces or passageways in the nasal cavity. The nasal cavity is the hollow space inside the nose, and it is divided into two sides by a midline nasal septum. Each side of the nasal cavity has three meatuses.
The meatuses are named according to their respective location within the nasal cavity. The three meatuses are known as the superior, middle, and inferior meatus. The superior meatus is the highest one, located above the middle meatus, while the inferior meatus is the lowest, found beneath the middle meatus.
These meatuses play an essential role in the proper functioning of the respiratory system. They are responsible for directing the airflow within the nasal cavity. The incoming air is humidified, warmed, and filtered as it passes through the meatuses, preparing it for entry into the lungs.
Additionally, the meatuses are also involved in the drainage of the paranasal sinuses. The middle and superior meatuses receive the openings of the frontal, ethmoid, and sphenoid sinuses, allowing mucus and other secretions to exit the sinuses and flow into the nasal cavity. This drainage is essential for maintaining sinus health and preventing sinusitis.
Overall, the meatus nasi is a critical anatomical feature that contributes to proper respiration, filtration, and sinus drainage, ensuring the overall health and functionality of the nasal cavity.
