Exam 2 Module 3 Flashcards
What is the Density of air molecules within a particular volume?
Air Pressure
If the volume is closed off then…?
squeezing that volume will increase air pressure
If the volume is open then…?
squeezing that volume will cause air to flow out to maintain normal pressure
The lungs are connected to the ___ and the ___.
diaphragm and the rib cage
Lung volume is controlled by the ____ and the ____.
diaphragm muscle and the muscle attacked to the ribs
What are these muscles called that controll lung volume?
Serratus anterior
intercoastal muscle
The contraction of the diaphragm raises and expands the rib cage causing the lungs to ____?
expand.
if the ____ is open, this will cause air to flow into the lungs to maintain normal pressure
vocal tract
Relaxing the diaphragm and ____the rib cage will contract the lungs and cause air to flow ______ .
contrating
//
out of the lungs
Lung volume and changes in lung volume can be measured to
quantify respiration
The measures of respiration can be used clinically to determine what?
To determine whether a person with voice problems has enough breath support from respiration to produce speech.
What letter in the English language does not require much articulation beyond respiration and is one of the simplest speech sounds.
/h/
LOOOK at “He ha Hu” image on desktop. This is the breakdown of sound into a frequency sprectrum overtime. What is the point of this picture.
The main point of this slide is to let us know that although each syllable begins with /h/, the noise pattern in the spectrogram for each is different because the oral cavity is already in position to produce the following vowel.
- While production of /h/ REQUIRES NO particular oral articulation, /h/ uses BOTH _____ & ______.
- The laryngeal muscle open up the ____ and the muscle of respiration produce _____.
- laryngeal and respiratory effort.
vocal folds// extra expiratory effort.
