a part of the nasal cavity that helps with drainage and airflow in the nasal passages, located between the inferior and superior meatuses
The middle meatus is an important structure found within the nasal cavity, specifically in the middle region. It serves as a conduit for the flow of air, as well as the drainage of secretions from the frontal, maxillary, and anterior ethmoid sinuses. The middle meatus is also home to various anatomical structures such as the ethmoidal bulla, which helps in humidifying and filtering the inhaled air. It plays a crucial role in maintaining the health and functionality of the respiratory system by ensuring proper airflow and drainage within the nasal passages.
