Answer:
The correct answer is "arytenoid".
Explanation:
The paired cartilages that articulate with the superior border of the cricoid cartilage are the arytenoid cartilages. Arytenoid cartilages are comprised of a pair of small three-sided pyramid that are attached to the vocal cords, along with the cricoid cartilage, a ring of cartilage that surrounds the trachea. Arytenoid cartilages are essential to the vocal cords' movement.
