Definition of hyoid in English:


(also hyoid bone)


Anatomy Zoology
  • A U-shaped bone in the neck which supports the tongue.

    • ‘Freeing the tongue from the hyoid removes a limit on tongue excursion imposed by the basic architecture of the mammalian feeding apparatus.’
    • ‘In most vertebrates the hyoid supports the tongue, as it does in the snake-necked turtle.’
    • ‘I included all muscles associated with the jaws, tongue and hyoid, palate, and pharynx.’
    • ‘Their contraction shortens the tongue towards its base on the hyoid.’
    • ‘The chimaeran hyoid is, it turns out, quite happy supporting the operculum and has no interest in the palatoquadrate.’


Anatomy Zoology
  • Relating to the hyoid or structures associated with it.

    • ‘The mechanism by which these fish capture prey involves upper jaw protrusion, lower jaw depression, hyoid depression, and cranial rotation.’
    • ‘The hypohyal is a ventral element of the hyoid arch which links the ceratohyal and the basihyal.’
    • ‘Speech requires flexibility of the upper airway, including laryngeal and hyoid mobility and separation of the hard palate from the epiglottis.’
    • ‘Again, we see that the mandibular and hyoid arches are developmentally different from the rest of the series.’
    • ‘These are formed from fused hyoid rays and articulate with the succeeding gill arches.’


Early 19th century: via French from modern Latin hyoïdes, from Greek huoeidēs ‘shaped like the letter upsilon (υ)’.
