Synonym: cricoarytenoid joint
English: , CAJ
Definition[Bearbeiten]
The articulatio cricoarytaenoidea is a joint between the base of the stellate cartilage (cartilago arytaenoidea) and the upper edge of the cricoid cartilage (cartilago cricoidea). The joint capsule is reinforced by the cricoarytaenoid ligament
Function[Bearbeiten]
The articulatio cricoarytaenoidea allows the two cartilages to move against each other, which - depending on the direction - causes the vocal cords and thus the glottis to widen or narrow.
Clinic[Bearbeiten]
Degenerative changes to the cricoarytenoid joint can occur in old age. Arthritic diseases are also possible.
