The term "superior nasal" refers to the superior nasal concha, a bony structure located in the nasal cavity. It is one of three conchae, which are curved bony projections that help to filter and humidify the air we breathe. The superior nasal concha is situated at the upper part of the nasal cavity and plays a role in the respiratory system. In addition to its anatomical significance, the superior nasal concha is associated with the ethmoid bone, which forms part of the skull. This structure contributes to the overall function of the nasal passages, aiding in olfaction, or the sense of smell, by increasing the surface area for air contact.
