Mucosal wave
What is the name of the muscle in the vocal folds?
Thyroarytenoid muscle
What is the Internal Thryoarytenoid called? How far from the glottis is it?
Vocalis
Near
What is the External Thryoarytenoid called? How far from the glottis is it?

The vocal folds are comprised of what three things?
Vocalis (Internal Thryoarytenoid)
Muscularis (External Thryoarytenoid)
Vocal Ligament
What are the false vocal cords called?
2
Ventricular folds
Ventricular ligaments
What is the entryway to the larynx called?
Aditus
What are the passive forces that influence the movement of the laryngeal apparatus?
(3)
Recoil forces
Surface tension
Gravity
What are the active forces that influence the movement of the laryngeal apparatus?
(2)
Intrinsic Muscles (those within the larynx)
Extrinsic Muscles (those with only one laryngeal attachment - usually to hyoid)
What is recoil?
Elasticity causing muscles to want to return to resting state
Can the vocal folds close themselves?
No. They rely on other muscles
Does the Thyroarytenoid aid in abduction/adduction?
No
What causes surface tension in the larynx?
2
Moisture
Mucosal membranes
