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. [WP,modified]. UMLS:C0020417 SCTID:263352000 Paired processes that extend posterolaterally from the posterior margin of the hyoid plate. These processes are the ossified posteromedial processes and invest the laryngeal apparatus.[AAO] hyoideum EMAPA:18650 MA:0001484 hyoid The hyoid bone is derived from the lower half of the second gill arch in fish, which separates the first gill slit from the spiracle. In many animals, it also incorporates elements of other gill arches, and has a correspondingly greater number of cornua. Amphibians and reptiles may have many cornua, while mammals (including humans) have two pairs, and birds only one. In birds, and some reptiles, the body of the hyoid is greatly extended forward, creating a solid bony support for the tongue. The howler monkey Alouatta has a pneumatized hyoid bone, one of the few cases of postcranial pneumatization of bones outside Saurischia. pharyngeal arch 2 pharyngeal arch 3 irregular bone hyoid apparatus
