" There are usually several of these plates in each nasal chamber. The upper ones, connected directly with the ethmoid bone, are called ethmoturbinals , and the lower, connected with the maxillæ, maxillo-turbinals . Incurved portions of the wall of the nasal chamber are sometimes called pseudoturbinals , to distinguish them from the true turbinals which are free outgrowths into the chambers." [1913 Webster]
