(重定向自Transverse arytenoid muscle)
The arytenoid/ærᵻˈtiːnɔɪd/ is a single muscle, filling up the posterior concave surfaces of the arytenoid cartilages.
It arises from the posterior surface and lateral border of one arytenoid cartilage, and is inserted into the corresponding parts of the opposite cartilage.
