hyoid bone
The hyoid bone (lingual bone) (;〔''Oxford English Dictionary'' 2nd edition, 1989.〕〔(Entry "hyoid" ) in ''(Merriam-Webster Online Dictionary )''.〕 Latin os hyoideum) is a horseshoe-shaped bone situated in the anterior midline of the neck between the chin and the thyroid cartilage. At rest, it lies at the level of the base of the mandible in the front and the third cervical vertebra (C3) behind.
Unlike other bones, the hyoid is only distantly articulated to other bones by muscles or ligaments. The hyoid is anchored by muscles from the anterior, posterior and inferior directions, and aids in tongue movement and swallowing. The hyoid bone provides attachment to the muscles of the floor of the mouth and the tongue above, the larynx below, and the epiglottis and pharynx behind.
Its name is derived .〔Dorland illustrated medical dictionary〕〔American heritage dictionary for english language〕
==Structure==
The hyoid bone is classed as an irregular bone and consists of a central part called the body, and two pairs of horns, the greater and lesser horns (or cornua).
