This larynx is comprised of nine cartilages. It is covered by mucosa to form the aryepiglottic fold. pg. It keeps the air passages open during breathing and digestion and is the key organ for producing sound. During swallowing, as the larynx moves up and forwards, the epiglottis swings downward to close off the laryngeal inlet, and thus prevents materials from entering the airway. Internal respiration is the exchange of gases between the blood in capillaries and the tissues of the body. The information we provide is grounded on academic literature and peer-reviewed research. pitch) depends on the length, tension, and position of the vocal folds.

The vocal apparatus of the larynx is called the glottis and consists of two vocal folds (true vocal cords) and the rima glottidis. It is formed superiorly by the pharyngeal tonsils, also known as adenoids, in the roof of the nasal pharynx. 447, d. the diaphragm and intercostal muscles relax, Which nonrespiratory air movement clears the upper respiratory passageways? All rights reserved. This membrane forms the free superior edge of the quadrangular membrane, which as described earlier, connects the arytenoid cartilages to the lateral borders of the epiglottis. It is a component of the respiratory tract, and has several important functions, including phonation, the cough reflex, and protection of the lower respiratory tract.
