Which muscle increases tension on the vocal cords?

Explanation:
The muscle that increases tension on the vocal cords is the cricothyroid. It works by tilting the thyroid cartilage forward relative to the cricoid, which lengthens the vocal folds. Longer, stretched vocal cords become taut, increasing tension and raising pitch. Other muscles have different roles: the thyroarytenoid relaxes and shortens the vocal cords, reducing tension; the lateral cricoarytenoid adducts the vocal folds (brings them together); and the posterior cricoarytenoid abducts the vocal folds (opens the glottis).
