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.
&fist; 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.
Tur"bi*nal, n. (Anat.) A turbinal
bone or cartilage.
