Which cartilage forms the anterior attachment of the vocal folds in the larynx?
Arytenoid cartilage
Thyroid cartilage
Cricoid cartilage
Epiglottis
What is the primary function of the intrinsic laryngeal muscles?
Swallowing
Controlling vocal fold movement
Supporting the trachea
Producing saliva
Which structure acts as a protective cover over the larynx during swallowing?
Arytenoid cartilage
Epiglottis
Cricoid cartilage
Hyoid bone
What is the space between the vocal folds called?
Vestibule
Glottis
Subglottis
Supraglottis
Which layer(s) of the vocal folds form the "cover" per the Cover-Body Model?
Epithelium
Superficial lamina propria
Vocalis muscle
Deep lamina propria
Which muscle is primarily responsible for abducting the vocal folds?
Cricothyroid
Posterior cricoarytenoid
Lateral cricoarytenoid
Thyroarytenoid
Which part of the larynx is located most inferiorly?
Thyroid cartilage
Epiglottis
Cricoid cartilage
Arytenoid cartilage
What is the primary role of the cricothyroid muscle?
Adducting the vocal folds
Tensing and lengthening the vocal folds
Relaxing the vocal folds
Abducting the vocal folds
Which cartilage forms a complete ring in the larynx?
Thyroid cartilage
Arytenoid cartilage
Cricoid cartilage
Corniculate cartilage
Which of the following is the only bone that is part of the laryngeal mechanism?
Hyoid bone
Cricoid cartilage
Arytenoid cartilage
Epiglottis
A singer wants to increase the pitch of their voice. Which muscle should they engage more?
Thyroarytenoid
Cricothyroid
Posterior cricoarytenoid
Lateral cricoarytenoid
Which of the following best explains how the myoelastic aerodynamic theory accounts for vocal fold vibration?
Vocal folds vibrate due to electrical impulses
Subglottal pressure and tissue elasticity interact to produce vibration
Vocal folds vibrate due to rapid muscular contraction
Sound is produced by the resonance of the oral cavity
A person with a paralyzed posterior cricoarytenoid muscle would have difficulty with which action?
Closing the vocal folds
Opening the vocal folds
Tensing the vocal folds
Relaxing the vocal folds
According to the myoelastic aerodynatic theory, what happens if subglottal pressure increases while the vocal folds are adducted?
the vocal folds will remain stiffly closed
Vibration will be initiated once subglottal pressure overcomes tissue elasticity
Pitch will decrease
No sound will be produced
Which scenario best illustrates the Bernoulli effect in voice production?
Airflow slows down as it passes through the glottis, causing the vocal folds to close
Airflow speeds up through the narrowed glottis, creating negative pressure that draws the vocal folds together
Vocal folds are pushed apart by muscle contraction
The tongue blocks the oral cavity, increasing pressure
If the vocal folds are lengthened and tensed, what happens to the pitch of the voice?
It decreases
It increases
It stays the same
It becomes irregular
Which of the following best describes the role of the thyroarytenoid muscle?
Lengthens the vocal folds
Shortens and relaxes the vocal folds
Abducts the vocal folds
Elevates the larynx
A person is unable to produce a loud voice. Which physiological factor is most likely reduced?
Medial compression of the vocal folds
Vocal fold length/tension
Laryngeal height
Cricothyroid function
Which of the following changes would most likely increase vocal pitch?
Decreasing vocal fold tension
Increasing vocal fold mass
Increasing vocal fold length and tension
Decreasing subglottal pressure
Label the image using the following choices.
Which cartilage provides the posterior attachment for the vocal folds?
Epiglottis
Arytenoid cartilage
Cricoid cartilage
Thyroid cartilage
What is the effect of increased subglottal pressure on vocal intensity?
Intensity becomes irregular
Intensity decreases
Intensity increases
Intensity remains unchanged
Which intrinsic laryngeal muscle is primarily responsible for adducting the vocal folds?
Thyrohyoid
Lateral cricoarytenoid
Posterior cricoarytenoid
Cricothyroid
What is the effect of decreased medial compression of the vocal folds during phonation?
Pitch increases
Voice intensity increases
Pitch decreases
Voice intensity decreases
