DIAGRAM: The diagram below shows a cross section of the neck, in which we can see the vocal chords (A) open during breathing and (B) closed during phonation (singing or speaking). The Hyoid bone (3) holds the front of the entrance of the larynx in place, while the Arytenoid and Corniculate cartilages make the vocal chords close the Glottis and block the breath. The vocal folds are fixed between the back of the Adam’s Apple (Thyroid cartilage) and the Arytenoid cartilages which move like wings on hinges to close the vocal chords together, and also flex them to provide higher pitched speech or singing. Their length in the relaxed position dictates they type of voice you have. The longer they are, the lower the vocal range. phonation - voicing, or product of vocal fold vibration in larynx biological function of larynx - Fxing the thorax for heavy lifting, childbirth, defecation. Bernoulli Effect - given a constant ±ow of air, at a point of constriction there will be an increase in pressure at the constriction, an increase in velocity of ±ow, and a decrease in air pressure perpendicular to the ±ow. larynx - musculo-cartilaginous structure at end of trachea, three paired/ three unpaired cartliages
