Intro test 1 p2 Flashcards
Thoracic cavity ( Respiratory System)
“Thoracic cage: rib cage” Had 12 pairs of ribs
Respiratory system
Process of breathing, Inhale and exhale, Produces air under pressure which generates speech
Diaphragm ( respiratory system)
thick muscle shaped like a dome
Pulmonary system (respiratory system)
cone shaped lung, includes upper and lower airways
Upper airway (respiratory system)
includes mouth nose and upper portions of throat
Lower airway (respiratory system)
includes the tracea
Respiratory stucture
Vocal cords sit right on top of trachea
phonate
To phonate is to produce voice
Phonotation
sub-glottal Air pressure, Bernoulli effect, myoelastic aerodynamic theory.
Variations in patterns of movement (Phonatory system)
Pitch- how high
Loudness how loud
larynx
a valve that opens and closes, sets molecules from breath stream into vibration ( vocal folds), sound production when phonation occurs.
when silenced are vocal folds open or closed?
open
Air molecules vibrating at a rate in a particular range
Air molecules vibrating at a rate in a particular range
phonatory muscles
-throaryteniod muscles, muscles that move the vocal folds
adductor
lateral cricoarytenoid
abductor
posterior
vocal fold vibration
is result rom buildup of air pressure below vocal fold which is responsible for making exhaled air vibrate.
