Conceptual integration & Phonation 1 (Chapter 5)
. The movement of the cricoarytenoid joints is
Primarily rocking
Elastic recoil forces are
Restorative forces acting upon the lungs and thorax to return them to their resting state
During the opening phase of vocal fold oscillation, the upper border of the vocal folds
Separates after the lower border
The mucosal wave is the term used to refer to
Vocal fold oscillation
The "Adam's apple" is the most prominent anterior point of the thyroid cartilage.
true
. During vocal fold oscillation, the vocal folds are pushed apart by the
Buildup of lung pressure
. The unpaired laryngeal cartilages, in order from inferior to superior, are the
Cricoid, thyroid, and epiglottis
In the body cover mechanical model of the vocal folds, the body consists of the
Epithelium and the superficial and intermediate layers of the vocal folds
During vocal fold vibration, the restorative forces of the vocal fold tissues
Help to return the vocal folds to their midline position
. The term vertical phasing or out-of-phase movement describes
The difference in directional movement of the upper and lower borders of the vocal folds during oscillation
. Equilibrium of the forces of inhalation and exhalation means that
The muscles of breathing are contracted and the forces are balanced
The abduction and adduction of the vocal folds is achieved by movement of the
Cricoarytenoid joints
Three features of vocal fold closure that are important in the regulation of intensity are
Duration, speed, and degree
Breathing in very humid air requires more work, in general, than breathing in air with low humidity because
Humid air is more viscous and generates greater frictional forces
In the three-layer mechanical model of the vocal folds, the vocal ligament consists of the
Intermedia and deep layers of the lamina propria
Research suggests that auditory feedback
Is an important component of overall sensory feedback that helps us control both fundamental frequency and intensity
During vocal fold vibration, the arytenoid cartilages
Maintain adduction of the vocal folds
The movement of the arytenoid cartilages is achieved through contraction of the muscles attached to the
Muscular processes
During vocal fold vibration, the air pressure below the vocal folds
Must be greater than the air pressure above the vocal folds
The Lombard effect tells us that
People tend to increase their vocal intensity when speaking within noise
. In the relaxation pressure curve, the top right quadrant represents
. Relaxation pressure working to decrease lung volume
. The Bernoulli effect tells us that
. The air pressure will decrease as the air flows through the vocal tract in an area of constriction.
cricothyroid joint
Allows the thyroid cartilage to rock forward and downward to achieve vocal fold elongation
The larynx is located
At the level of the cervical vertebrae
The hyoid bone
Attaches to the base of tongue via muscles and ligaments
The paired arytenoid cartilages articulate with the cricoid cartilage by means of the _______ joint.
cricoarytenoid
The cricothyroid joint results in cartilage movement upon contraction of the ______ muscle.
