QUIZ 1 Flashcards
instrumentation
equipment or software that allows a clinician or researcher to acquire and analyze physiological or acoustic data objectively
advantages of instrumentation
objective- attain pre and post therapy data
disadvantages of instrumentation
expensive- to buy initially; to upkeep
time consuming
after experience, trust your ears
best use of instrumentation
ideal- to use our auditory perception simultaneously with instrumentation
its the best combo of what we hear and the analysis of voice (or the #s we get)
respiratory system
- air needed to drive voice
- vocal fold movement
- different sounds
laryngeal system
responsible for voicing
velopharyngeal system
responsible for nasal sounds
vp= active when closed (it takes effort to close/contract the port)
vp=inactive for nasals/ port is open
articulatory system
main speech producer
upper vocal tract (lips, teeth, tongue)
makes speech intelligible
trachea
entrance to the bronchi
HYALIN CARTILAGE
c-shaped rings that are open in the back ; trachealis muscle separates rings from the esophagus
trachea function
conduct air in most effortless way possible
bronchi
HYALIN CARTILAGE AND SMOOTH MUSCLE
compliant tubes lined with respiratory mucosa
bronchi function
conduct air
undergo constriction and dilation
filters foreign particles
10,000L of inspired air/day
bronchioles
SMOOTH MUSCLE (1ST region that lack cartilage)
bronchioles function
conduct air/ produce secretions
participate in gas exchange
alveoli
reticular (tiny collagen fibrils) and elastic fibers
