Muscles
Looks like
The front, more upright part of the cricothyroid muscle, running from the front of the cricoid ring up to the lower edge of the thyroid cartilage.
What it does
Tilts the thyroid cartilage down toward the cricoid, stretching the vocal cords to raise the pitch.
Keeping it well
Powered by the external laryngeal nerve, which surgeons protect in thyroid operations. Singers notice weakness first as lost high range.
