The nasal cavity is part of the upper respiratory tract located above and behind the nose. The nasal cavities are elongated wedge-shaped spaces with a large inferior base and a narrow superior apex. They are held open by skeletal framework consisting mainly of bone and cartilage. The two cavities are separated by the nasal septum. The bony borders of the nasal cavity and their adjacent alar cartilages make up the center of the face.

The surface of the lateral wall of the nasal cavity is irregular in contour and is interrupted by three nasal conchae – the superior nasal concha, the middle nasal concha and the inferior nasal concha. These structures are long, narrow curled shelves of bone that protrude into the nasal cavity. They are covered by a mucus membrane and the epithelium that lines them is pseudostratified columnar ciliated respiratory epithelium. The conchae are responsible for the majority of airflow direction, humidification, heating and filtering of the air inhaled through the nose.

In the full version of this tutorial, we will look in more detail at the lateral wall of the nasal cavity, which is rather complex and formed by bone, cartilage and soft tissues. We will look at:
general anatomy of the nasal cavity;
bones and cartilages of the nasal cavity;
mucosa of the nasal cavity.
