Semi-rigid tube bounded superiorly by the hyoid bone and posteriorly by this cartilage.
What is the larynx?
100
Number of cartilages within the larynx.
What is nine?
100
The dome shaped muscle separating the chest from the abdomen
What is the diaphragm
100
Amount of air in the lungs at a given time.
What is lung volume?
100
Muscles that convert aerodynamic power to acoustic power
What are the vocal folds?
200
Spongy pliable sacs suspended within the rib cage.
What are the lungs?
200
Number of bones in the larynx?
What is one?
200
The larynx, trachea, bronchi, and lungs
What is the lower airway?
200
Air pressure inside the lungs
What is alveolar pressure?
200
Theory, published in the 1950’s, describes the initiation and maintenance of vocal fold vibration
What is the Myoelastic Aerodynamic Theory?
300
Bounded by the UES and the LES.
What is the esophagus?
300
Closes and protects lower airway from food and/or other foreign materials.
What are the vocal folds?
300
Area where the trachea bifurcates into the bronchial tubes.
What is the carina?
300
Air pressure outside the lungs
What is atmospheric pressure?
300
Principle that explains that as airflow enters an area of constriction, the flow of air increases in velocity but the pressure of the flow drop.
What is the Bernoulli Effect?
400
Area involved in tuning the acoustic signal and is open during the swallow
What is the pharynx?
400
Largest cartilage of the larynx.
What is the thyroid cartilage?
400
Muscles that span the distance between adjacent ribs and pull them together when contracted.
What are the intercostals?
400
Occurs when alveolar pressure greater than atmospheric pressure
What is exhalation?
400
The result of pressure drops above the level of the vocal folds during phonation
What is vocal fold adduction?
500
16 to 20 cartilaginous rings; closed in front, open in the back
What is the trachea?
500
Area that contains lubricating glands for the vocal folds.
What are the ventricles?
500
Nerve that courses from C3-C5 traveling downward in the neck to the posterior mediastinum, between the lungs, past the heart, and inserting into the diaphragm.
What is the phrenic nerve?
500
The volume of air inhaled and exhaled during any single respiratory cycle.
What is tidal volume?
500
Pressure below the vocal folds when adducted and ready for phonation?
