Etymology: "Ethmoturbinal" is a plain technical compound, built from "ethmo-", a combining form from the Greek "ēthmos," meaning sieve, and "turbinal," the adjective formed from "turbinate," itself from the Latin "turbo," a spinning top or whirl. The Latin "turbinatus" referred to something shaped like a top, and anatomists used the "turbinate" family of terms for the scroll-shaped bones inside the nose. Together the parts describe the ethmoid bone, the sieve-like bone at the top of the nasal cavity, and its turbinate structures, the thin curled bony plates that project into the nasal passages. The word is therefore an anatomical descriptor, used to say that a feature belongs to the ethmoid bone's turbinate region rather than to another part of the skull or nose.
