There are two small cartilages which are not seen inthis figure, called arytenoid cartilages, from two Greek words,meaning ladle and shape, because they bear some resemblancein form to a ladle. They stand in the open space in the rearpart of the thyroid, on the top of the cricoid cartilage. Theyare the pillars to which the vocal chords or ligaments are attachedbehind. These two cartilages are movable, having a regularjoint with the upper edge of the cricoid. There are small mus-cles which pull them in different directions, and thus changethe degree of tension and the position of the vocal ligaments,and of course vary the note of the sound produced by their vibra-tion. That you may understand how this is done, I give you. 250 HUMAN PHYSIOLOGY. Vocal ligaments. Mode of their action.
