PCSD 313 Exam #2 Phonation & Respiration (Laryngeal) Practice Questions and Study Guide |
Communication Sciences Review
phonation - correct answer ✔✔the sound that is produced at the level of the larynx and vocal
folds are responsible for producing phonation/voicing
valving - correct answer ✔✔abduction and adduction of vocal folds & how vocal folds produce
voicing
when vocal folds valve the air stream - correct answer ✔✔air will flow through the glottis in
bursts
voicing requires what? - correct answer ✔✔muscular and aerodynamic forces
2 phases of phonation - correct answer ✔✔prephonatory phase and attack phase
2 parts of prephonatory phase - correct answer ✔✔vocal fold approximation
medial compression
3 parts of attack phase - correct answer ✔✔bernoulli effect
initiation of phonation
vocal attacks
Vocal fold approximation - correct answer ✔✔movement of the vocal folds towards the midline
(requires use of adductor muscles)
medial compression - correct answer ✔✔extent of force with which vocal folds are brought
together at midline (they don't have to completely adduct)
, Bernoulli Effect - correct answer ✔✔vocal folds provide a source of constriction in the vocal
tract & the constriction produced will cause the air flowing through the folds to increase in
velocity
what is the larynx superior to? - correct answer ✔✔the trachea
where are vocal folds housed? - correct answer ✔✔the larynx
initiation of phonation - correct answer ✔✔As subglottal pressure overcomes vocal fold
compression, the folds are blown apart to release a puff of air;
Elasticity and the Bernoulli effect cause the vocal folds to snap back together medially
Vocal Attacks - correct answer ✔✔the way in which respiration and the laryngeal systems are
coordinated
vocal attacks: simultaneous - correct answer ✔✔A balance between respiration and laryngeal
action- Air stream is released just as the VFs meet at midline
Vocal Attacks: Breathy - correct answer ✔✔significant air flow escapes through the vocal folds
BEFORE they are adducted
vocal attacks: glottal - correct answer ✔✔adduction of the vocal folds occurs BEFORE air flow
begins
when pitch changes - correct answer ✔✔vocal folds appearance change
to raise pitch - correct answer ✔✔increase vocal fold length
