Voice Pathophysiology

Question 1

What would happen if the oblique arytenoid muscle was not functioning

Answer 1

Problems with vocal fold adduction, resulting in a breathy and hoarse voice

Question 2

What would happen if there was problems with the vocalis muscle

Answer 2

Client would have difficulty adjusting pitch, difficulty with loudness control, vocalis muscle loosens the tension of vocal folds,

Question 3

muscle responsible for abduction of vf

Answer 3

posterior cricoarytenoid

Question 4

muscles responsible for adduction of vf

Answer 4

transverse and oblique arytenoid and

Question 5

function of lateral cricoarytenoid

Answer 5

pulls muscular process forward, part of adduction

Question 6

What nerve is responsible for laryngeal innervation

Answer 6

The superior and recurrent laryngeal nerves from the vagus nerve (CN10)

Question 7

Main function of superior laryngeal nerve

Answer 7

Innervates cricothyroid muscle, innverates sensory receptors in larynx

Question 8

How does vocal fold length effect pitch

Answer 8

Long vocal folds/ lower tension = low pitch
Short vocal folds = high pitch

Question 9

what causes audible inspiration

Answer 9

inadequate abduction

Question 10

how would the damage of the superior LN impact pitch

Answer 10

may have difficult altering pitch, if unilateral may cause diplophonia
