Voice Flashcards
When are the false folds used?
during lifting and coughing, not speech
Where do the aryepiglottic folds lie and what do they do?
above ventricular folds, seperating the pharynx and laryngeal vestibule, help preserve the airway
What innervates the posterior belly of digastric?
Facial nerve
What innervates the cricothyoid?
superior laryngeal nerve of vagus
What innervated the other laryngeal muscles?
recurrent laryngeal nerve of vagus
What is the vascular supply to the larynx?
superior laryngeal, cricothyroid, and inferior laryngeal arteries
What are infrahyoids?
thyrohyoid, omohyoid, sternothyroids, sternohyoids.
What are suprahyoids?
digastrics, geniohyoids, mylohyoids, stylhyoids, genioglossus, hyoglossus
What is MFF of 7-8, 9-10 year olds?
281-297, 238-270
What is MFF of nineteen year olds?
217 female, 117 male
What is the MFF for men and women?
100-150, 180-250 (125 & 225)
What is MPT for adults?
20.0-24.6 sec
What are age related changes to the voice?
hardening of laryngeal cartilages, degeneration and atrophy of laryngeal muscles, degenrative changes in lamina propria, deterioration of cricoarytenoids and conus elasticus
What is presbyphonia?
age-related voice disorder characterized by perceptual changes in quality, range, loudness, and pitch
How is pitch detemined?
By mass, tension, and elasticity of the vocal folds. A high pitch has thinner, more tense vocal folds. A lower pitch has thicker more relaxed folds.
What is jitter?
variation in vocal frequency often heard in dysphonic patients. Less than 1% jitter is normal
What is shimmer?
variation in loudness.
Why are measures of jitter and shimmer useful?
the can assist in early detection of vocal pathology
How does a hoarse voice typically sound?
breathy, low-pitched, adn husky. Also there are pitch breaks and excessive throat clearing. Hoarseness results from irregular vocal fold virbations
What is strain-strangle?
effortful phonation, patient sounds like they are squeezing voice at glottal level, talking fatigues patients
What is breathiness?
results from the vocal folds being slightly open. Due to organic or inorganic causes, SOFT WITH LITTLE VARIATION IN LOUDNESS. pATIENTS SHOW RESTRICTED VOCAL RANGE.
