What is the function of the extrinsic laryngeal muscles?

• A. Stabilize the larynx and elevate/depress the larynx
• B. Stabilize the larynx and rotate the larynx
• C. Move the larynx up and down without stabilization
• D. Elevate only

Answer: (D)

Extrinsic laryngeal muscles attach the larynx to surrounding structures (like the hyoid bone and the sternum) and move the larynx as a whole, not the laryngeal parts themselves. Their main role is to stabilize the larynx in the neck and to elevate or depress it as needed during activities such as swallowing and phonation. Some muscles lift the larynx, while others pull it downward, providing the vertical positioning that supports airway protection and voice function. They do not act to rotate the larynx, and their action isn’t limited to elevation alone. Intrinsic laryngeal muscles, by contrast, adjust tension and opening of the glottis, which is a different level of control.
