The âfalseâ vocal folds or cords are placed above the real vocal cords and prevent the substances like food from entering inside trachea while we are swallowing it. They are not in any way related to the function of singing or speech.
Larynx, also called voice box, a hollow, tubular structure connected to the top of the windpipe (trachea); air passes through the larynx on its way to the lungs. The larynx also produces vocal sounds and prevents the passage of food and other foreign particles into the lower respiratory tracts. The larynx is composed of an external skeleton of cartilage plates that prevents collapse of the structure. The plates are fastened together by membranes and muscle fibres.
