The |nasal cavity| is in the middle of the face and is formed by a number of bones. The |nasal bone| forms the roof, while the sides are formed by the ethmoid and maxillary bones. Within the |nasal cavity| is a vertical plate, or |septum|, which divides the cavity into two halves. The top and front of the |septum| is made of the vertical plate of the |ethmoid bone|, while the bottom and back of the |septum| is formed by the vomer. Each side of the |nasal cavity| features three curved ledges, called turbinates or conchae. The superior and middle turbinates are protrusions from the |ethmoid bones|, while the inferior turbinate is attached to the maxillary bone. The back of the |nasal cavity| opens just behind the |palatine bone|. The |nasal cavity| also has a ~mucous~ lining, which features thousands of tiny |cilia| which filter dust from the ~air~. The |cilia| constantly move ~mucous~ and dust to the back of the |nasal cavity| and into the |pharynx|, whereupon it is swallowed.
