Functional Larynx,
English
2.5 times full-size
This model shows the structure of the larynx and the relative position to the larynx of the thyroid gland, of
which the left lobe is presented. The larynx is one of the respiratory organs. The epiglottis can be moved
to demonstrate how the epiglottis closes down over the aperture of the larynx during swallowing, sealing
off the lower respiratory tract. The larynx is furthermore used to generate the voice. The flexible arytenoid
cartilage and vocal chords enable impressive demonstrations of how the true glottis dilates and constricts
during movements of the cricoarytenoid joint.
