2) дилататорлар (кенгайтирувчи); 3) овоз бойлами таранглигини узгартирувчилар. Thyroid cartilage. (cartilago thyroidea). Thyroid and cricoid cartilages. (cartilage thyroidea) (cartilago cricoidea). Laryngeal inlet Хикилдокка кириш (aditis laryngis) Хикилдок (larynx) ва калконсимон без (glandulathyreoidea). Internal structure of larynx . While the hyoid muscles (suprahyoid and infrahyoid muscles, see Chapter4: Head and Neck) raise and lower the larynx, the intrinsic laryngealm muscles move parts of the larynx against each other. The triated, that is voluntary, laryngeal muscles can open and close the glottis as well as change the tension of the vocal cords. All laryngeal muscles are innervated by cranial nerve X (vagus nerve). The posterior cricoarytenoid muscle is the only (!) opener (abductor) of the glottis, and it runs from the lamina of the cricoid posteriorly to the muscular process of the arytenoid. It opens the glottis for the passage of inspired air. All the other muscles narrow the glottis (lateral cricoarytenoid muscle, thyroarytenoid muscle, oblique and transverse arytenoid muscles).
