Practice quiz Flashcards
cranial nerves in speech production
V, VII, X, XII
how does the corticobulbar tract project brainstem’s motor nuclei
bilaterally: one side of the brain innervates left and right brainstem nuclei in parallel
lower motor neuron lesion causes
flaccid paralysis or paresis
motor neurons innvervating muscles of mastication reside in which brainstem nucleus
motor nucleus of trigeminal system
lateral cricoarytenoid does
medical compression during vocalization and rotates muscular process of arytenoid laterally
mentalis originates and inserts
in mandible and inserts into lower lip
buccinator originates and inserts
maxilla and inserts by integrating with muscles of oral angle
medial pterygoid muscle
closes the jaw
antagonist of medial pterygoid
anterior belly of digastricus
velopharyngeal muscles include
levator veli palatini, tensor veli palatini, and superior pharyngeal constrictor
role of levator veli palatini muscles in velopharyngeal port closure
elevate and retract velum posteriorly
role of pleural linkage in respiratory system
translation of rib movement through activation of respiratory muscles, into lung volume changes
factor affects lung volume
age
air remaining inlungs at the end of maximum expiration
residual volume
max air that can be forcefully expired after max inspiration
vital capacity
internal intercostal segment operates lower ribs
interosseous
relaxation pressure curve illustrates
lung pressure created by passive elastic recoil and rebounding forces of lung wall system
changes in alveolar pressure produced by passive recoil and rebounding forces constitutes breathing apparatus
vocal tract: open? closed?, etc?
pliable tube with one end open
sealed end is the closed glottis, open end, the oral or nasal opening
spectrographic patterns of nasalized vowels vs non-nasalized
absence of sound energy at certain frequency
peaks in vowel output spectrum with max energy transfer
formants
vowel quadrilateral demonstrates
low vowels have higher F1 than high vowels
oscillation of a particle around its rest position as result of recoil and inertial forces
simple harmonic motion
resonance object tends to vibrate with ______ energy at ______.
max energy at a particular frequency
period and frequency are _____ related
inversely
formants are resonants of the vocal tract that
change in value according to alterations in shape of vocal tract
position of the second formant for a given vowel (relative to the first formant) is mostly related to changes in:
volume of oral cavity
3 quantitative measures depicted by a spectrogram
frequency amplitude, time
sound occur least in english of:s, d, l, sh, z
“sh”
difficult for children with high frequency hearing loss to percieve
/s/ (high frequency noise)
vowel most similar to /j/
/i/ (tongue posture is high, front
first sound has a long-lag voice-onset time out of: ten, boy, sing, dog, lion
ten
long-lag voice-onset time is characteristic of
word initial voiceless stops
example of rapid, ballistic tongue movement
-ing, k, t, m
sound which production differs with blind and sighted children from: t, k, p, s, g
p: blind produce significantly lower proportion of bilabial sounds
bucket handle rib rotation
result in a large change in a mediolateral volume of the thorax
