These folds are on the sides of the larynx, There are four folds, or cords, two above, one on each side, called the false cords, and two below, one on each side, called the true cords. Their edges are smooth, and are quite sharp. When sound is being made by them, they nearly meet across the larynx. 105. How the Voice isMade.—During ordinarybreathing, no sound of thevoice is made; in such cases,the cords are not stretchedtightly across the opening ofthe larynx, but are relaxed,and the air passes through thelarynx without obstruction. In order to make a sound, wedraw the cords tightly, and, by stretching them, make themdraw close together, so as nearly to close the passagethrough the larynx. Their edges almost touch, and are thinand tight. While in this condition, we force the air b
