Musculus vocalis · Hlasivkový sval
Muscles
Looks like
The innermost part of the thyro-arytenoid muscle, lying right alongside the vocal ligament inside each vocal cord.
What it does
Fine-tunes the tension and stiffness of the vocal cords, shaping pitch and voice quality.
Keeping it well
Shouting and heavy voice use strain it; hydration, rest and good technique help. Hoarseness lasting over 3 weeks needs an ENT check.
