Etymology

In English, this muscle’s name means the muscle that lifts the thyroid gland. The term levator comes from the Latin verb levare meaning “to lift.” Thyroid is from the Greek term thyreos for “shield” plus the suffix eidos meaning “shape or form.” The Greek word thyreos comes from thyra meaning door and referred to a large, oblong stone that was used as a door. The term thyreos was later used to refer to large oblong shields used by Minoan warriors. The shields covered them from shoulders to feet, with the top of the shield having a notch for the chin. It was this shield that the ancient anatomist Galen envisioned when he named the laryngeal cartilage in the 2nd Century. Glandulae refers to a gland and comes from the Latin glans or glandis, which means acorn or acorn-shaped.
