A specific function of larynx represents the creation of voice-phonation, whose mechanisms are not as of yet sufficiently known. Thus, quite a lot of physiological phenomena cannot be properly recognized. Some anatomical details are not described at all and in the figure part of literature are left out in spite of their evident existence. These critical remarks pertains wholly to the up to date's knowledge of the role of the pseudo voice ligaments. The very existence of the pseudo voice ligament rather puzzles. The pseudo vocal fold are supposed to be immobile. There's a good reason to suppose that the pseudo voice ligaments follow a very important movent, though unnoticeable, in the direction of the elastic fibres, right at the phonal position. The fibres of the pseudo voice ligaments are drawn dorsally at which they draw upsligh the thyroid cartilage. It looks like the elastic fibres of the pseudo voice ligaments were functioning as a centering mechanism known with the electro-acoustical systems. As if this arrangement was to bring the thyroid cartilage in its role of a membrane into such position in which it could vibrate in both its directions, dorsal and ventral. The pseudo glotic ligaments represent at the same time a part of an arresting arrangement which damps in its respiration position the flexible prestress of the thyroid cartilage. If it were not so, the thyroid cartilage would vibrate automatically even in respiration producing at the same time unwanted sounds.
