COPD Larynx: cartilaginous tube; surrounds/ protects glottis (voice box); three large cartilages (epiglottis, thyroid cartilage, cricoid cartilage) a. Epiglottis: projects superior to glottis; forms lid over it i. What is the most common cause of lung cancer? Rotational movements of the arytenoid cartilages at the cricoarytenoid joints can separate (abduct) the vocal folds, widening the rima glottidis or appose (adduct) the vocal folds and narrow the rima glottidis.

The lymphatic vessels above the vocal folds drain into the superior deep cervical lymph nodes whereas those below the vocal folds drain first to nodes around the trachea (pretracheal and paratracheal nodes) and subsequently into the inferior deep cervical lymph nodes. 440, The function of the C-rings of hyaline cartilage in the trachea is to keep the airway patent or open for breathing. Serves as attachment points for several muscles.
