Correct answer: E — Cricoid cartilage
The paired arytenoid cartilages sit on and articulate with the superior border of the posterior cricoid cartilage via the cricoarytenoid joints. These synovial joints allow rotation and sliding movements that control vocal cord position. The vocal processes project anteriorly and attach to the vocal ligaments.
