ethmoturbinals

Turbinal \Tur"bi*nal\, a. [L. turbo, turben, -inis, a top,
   whirl.] (Anat.)
   Rolled in a spiral; scroll-like; turbinate; -- applied to the
   thin, plicated, bony or cartilaginous plates which support
   the olfactory and mucous membranes of the nasal chambers.
   [1913 Webster]

   Note: 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 maxillae,
         {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.
