In anatomy, a nasal concha (or turbinate) is a long, narrow and curled bone shelf (shaped like an elongated sea-shell) that protrudes into the breathing passage of the nose. Turbinate bone refers to any of the scrolled spongy bones of the nasal passages in vertebrates.


Nasal concha are any of several thin, scroll-shaped bony elements forming the upper chambers of the nasal cavities.

Bones called nasal conchae project into the nasal cavity, forming a series of folds (turbinates) that increase the surface area.
