title: The investigations of mechanical properties of ossificating thyroid cartilages of the human larynx.
abstract: 40 thyroid cartilages were used to investigations, they were taken from bodies of people, died between the ages of 19-99, by the use of the endurance machine with controlled speed of the increase of deformation. It was observed that the durability for flexion and the inflexibility of the investigated cartilages depends on the level of the process of their ossification, that is estimated by the help of the radiological index of the ossification (RIO). On the other hand, the searches of durability forcing of the regions of cartilages that presented different levels of the ossification process, proved the heterogenicity of the structure of the cartilage, in which ossified parts are separated by zones, that did not submit to this process.
