200

These muscles have one attachment on a non-laryngeal structure and they elevate or depress the larynx. They are also important in swallowing.

What are extrinsic laryngeal muscles?

200

This is the space between the aditus and the ventricular folds.

What is the vestibule?

300

Bands of tissue that can be moved into and out of the airstream to produce voiced or voiceless sound.

What are vocal folds?

This is responsible for sensation and motor function in the thorax, neck, and abdomen.

What is the vagus nerve?

300

This is the space between the true and false (ventricular) vocal folds.

What is the laryngeal ventricle?

All of the intrinsic laryngeal muscles are paired except for this one.

What is the transverse arytenoid muscle or transverse interarytenoid muscle?

500

This anterior portion of the laryngeal ventricle contains more than 60 mucous glands that aid in lubricating the vocal folds as well as helping to eliminate food particles that get into the airway.
