[Functional anatomy of a completely ossified hyoid apparatus in man. Study with cineradiography]

Radiocinematographic study of the laryngo-pharyngeal area in a man showing an entirely ossified hyoid system, made during the course of chewing, swallowing, and sound utterance. Two facts seem noteworthy: 1) from the morphological point of view, we should search in organogenesis for an explanation of the ossification of the hyoid apparatus; 2) from the functional point of view, one notes considerably reduced movements of the bone, without any change in the swallowing, or in the speach functions.
