Info

Larynx • Second sphincter formed by ventricular folds – Not normally active during phonation – Can become hyperfunctional during episodes of increased vocal effort/extreme vegetative closure – Directly superior to ventricle/true vocal folds – Form double layer of medial closure w/TVFs if needed – Principle function is to increase intrathoracic pressure by blocking exhalatory airflow from lungs – Compress tightly during sneezing/coughing, lifting, emesis, childbirth, defecation – Also provide medial level of airway protection during swallows
Larynx • Most inferiorly are true vocal folds – Provide vibrating source for phonation – Also close tightly for nonspeech and vegetative tasks • Thus, larynx and vocal folds function as variable valve – Modulate airflow through VFs during phonation – Close off trachea/lungs to prevent soiling of airway during swallows – Provide resistance to increased abdominal pressure during effortful activities
