Encyclopedia Article for nasal-concha

nasal concha

any of several thin, scroll-shaped bony elements forming the upper chambers of the nasal cavities. They increase the surface area of these cavities, thus providing for rapid warming and humidification of air as it passes to the lungs. In higher vertebrates the olfactory epithelium is associated with these upper chambers, resulting in keener sense of smell. In humans, who are less dependent on the sense of smell, the nasal conchae are much reduced. The components of the nasal conchae are the inferior, medial, superior, and supreme turbinates.
