Voice Flashcards
In the cover-body theory of phonation, what is thecover
Epithelium
Superficial, intermediate, and deep layers of lamina propria
which nerve innervates the posterior belly of the digastric
VII
What does the internal branch of the SLN innervate
sensory info
what arteries supply the larynx
superior laryngeal
cricothyroid
inferior laryngeal
which are the 5 intrinsic laryngeal muscles
- thyroarytenoid
- cricothyroid
- posterior cricoarytenoid
- lateral cricoarytenoid
- interarytenoid (transerves and oblique)
which muscles depress the larynx
- thyrohyoid
- omohyoid
- sternothyroid
- sternohyoid
which muscles elevate the larynx
- digastric
- geniohyoid
- mylohyoid
- stylohyoid
- genioglossus
- hyoglossus
what is the mean fundamental frequency of a child
age 7 to 8; 281 TO 297 HZ
age 10 to 11: 238-270 HZ
what are the max phonation times for children
- age 3-4: 7.5 to 8.95 sec
2. age 5-12: 14.97 to 17.74 sec
what is the fundamental frequency of men
100-150 Hz or approx 125
what is the fundamental frequency of women
180 to 250 or approx 225
what is the max phonation time for adults
20.9 to 24.6 seconds
what happens to men’s and women’s fundamental frequency as they age
women lower to 201 and men raise to 132-146
what are age related changes in the larynx
- hardening of cartilages
- degeneration and atrophy of muscles
- degeneration of mucosa
- decreased flexibility of cricoarytenoid joint
what is presbyphonia
age related voice disorder characterized by perceptual changes in quality, range, loudness, and pitch
what is assessed in voice
- pitch
- loudness
- quality
what is fundamental frequency
vibration of the vocal fold
what determines the pitch of the vocal fold
- mass
- tension
- elasticity
what is jitter
irregular vibration of the vocal fold
what is shimmer
cycle to cycle variation in amplitude
more than 1 dB variation makes someone dysphonic
what is hoarseness
combination of breathy and harsh from irregular vocal fold vibration
sound low pitched breathy and husky
what is harshness
rough, unpleasant, gravelly
associated with excessive muscular tension.
folds too tightly adducted and air released too abrupt
what is a strain-strangle quality
phonation is effortful
patient sounds as if squeezing the voice at the gottis
initiating and sustaining voice difficult
what is breathiness
breathy voice from folds being slightly open
often quiet with little variation in loudness
restricted vocal range
