[ 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. [ 1913 Webster]
