What causes adduction of vocal cords?

Contraction of the thyroarytenoid, interarytenoid, and lateral cricoarytenoid muscles causes adduction of the vocal cords. The respiratory movements of the vocal cords are coordinated with those of the diaphragm and other muscles of the ventilator pump.

What are the adductor muscles of the larynx?

The adductor muscle group is made up of the lateral cricoarytenoid muscles and the transverse arytenoid muscles. The muscles that govern abduction are the posterior cricoarytenoid muscles. The sphincter muscles are the transverse arytenoid muscles, the oblique arytenoid muscles and the aryepiglottic muscles.
