Normal Anatomy
Nose
The nose is divided in two by the nasal septum and reaches up to the nasopharynx. The nasal septum consists of both bone tissue and cartilage.
The nasal conchae (= turbinals) are thin bony curled bulges covered with mucosa: inferior nasal concha, middle nasal concha and superior nasal concha.
The conchae create the various nasal passages: the inferior, middle and superior nasal meatus (fig. 1).
