Which cartilage belonging to the larynx anchors the vocal cords?

The arytenoid cartilage anchors the vocal chords. It is a pair that looks like a pyramid needed for the voice sound production. It sits on the upper part of the cricoid cartilage posterior part. The arytenoid has body, muscular process, apex and the vocal area and the vocal is the only thing that is clear if doing endoscopy in the larynx.
