Mucosal wave

6

What is the name of the muscle in the vocal folds?

Thyroarytenoid muscle

Vocalis

Near

8

Vocalis (Internal Thryoarytenoid)

Muscularis (External Thryoarytenoid)

Vocal Ligament

10

What are the false vocal cords called?

(2)

Ventricular folds

Ventricular ligaments

11

What is the entryway to the larynx called?

Aditus

12

What are the passive forces that influence the movement of the laryngeal apparatus?

(3)

Recoil forces

Surface tension

Gravity

13

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)

14

What is recoil?

Elasticity causing muscles to want to return to resting state
