<span>Nasal conchae and meatuses Nasal conchae, also known as nasal turbinates, are curved shelves of spongy bones forming in the walls of human nose.

The nasal conchae divides the nasal cavity into ducts or meatuses, this are <span>the passages in the nasal cavity formed by the projections of the nasal conchae.</span></span>
