Q

what mucles are involoved with pitch and tension

A

vocalis muscle and cricothyroid muscle

17
Q

what is the function of the vocalis muscle

A

Alters vocal fold tension/relaxation during speaking or singing

18
Q

what is the function of the cricothyroid muscle

A

tilts the thyroid cartilage - increasing tension of vocal folds

19
Q

what does the recurrent laryngeal nerve innervate

A

all muscles reponsble for voicing except the cricothyroid (pitching)

20
Q

what is the cricothyrioid muscle innervated by

A

superior laryngeal nerve

21
Q

what is the function of the vocal fold mucosa

A

jiggles over the stiffer lower layers, giving rise to the mucosal wave

22
Q

what is part of the vocal fold mucosa

A

epithelium, basement membrane, Reinke’s space

23
Q

how is the glottis affected by pitch

A

high pitch - narrow glottis
low pitch - wide glottis

24
Q

what are the factors of voice modulation

A

Duration, Intensity, Loudness, Pitch, Tone
