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.
