Thyrovocalis muscle is attached to ____ process of the arytenoid cartilage.

Explanation:
Thyrovocalis attaches to the vocal process of the arytenoid cartilage. The vocal process projects forward toward the thyroid cartilage, and this is the insertion point for the medial part of the thyroarytenoid muscle. Contraction of thyrovocalis tense the vocal folds by pulling the arytenoid and thyroid cartilages closer, raising pitch. The muscular process is the lateral projection where the other part of the thyroarytenoid (thyromuscular) attaches, so that is not the insertion for thyrovocalis. The styloid is not part of the arytenoid, and there isn’t an “inferior” process to consider.
