Quiz 5 Questions Flashcards
Which of the following statements about the thyroid cartilage is TRUE?
a) It is the only complete ring-shaped cartilage in the larynx.
b) It serves as the primary point of attachment for the vocal folds as well as the epiglottis.
c) Its superior horns attaches with the cricoid cartilage at the facets for thyroid cartilage.
d) It attaches directly with the arytenoid cartilages in the posterior side.
b) It serves as the primary point of attachment for the vocal folds as well as the epiglottis.
Which of the following best describes how the cricothyroid (CT) muscles contribute to pitch differences?
a) The CT muscles rotate the arytenoid cartilages, thereby increasing the vocal fold tension which, in turn, increases the pitch.
b) The CT muscles increase subglottal pressure, which directly controls pitch without affecting vocal fold length or tension.
c) The CT muscles contract, tilting the thyroid cartilage forward and stretching the vocal folds, which increases tension and raises the pitch.
d) The CT muscles relax the vocal folds, making them shorter and thicker, which lowers the pitch.
c) The CT muscles contract, tilting the thyroid cartilage forward and stretching the vocal folds, which increases tension and raises the pitch.
Which of the following statements is FALSE?
a) The LCA muscle originates from the lateral aspect of the cricoid cartilage and inserts into the muscular process of the arytenoid cartilage.
b) The PCA muscle originates from the posterior surface of the cricoid cartilage and inserts into the muscular process of the arytenoid cartilage.
c) The LCA muscle, by pulling on the muscular process of the arytenoid cartilage, rotates the arytenoids to adduct the vocal folds.
d) The PCA muscle, by attaching to the vocal process of the arytenoid cartilage, helps abduct the vocal folds.
d) The PCA muscle, by attaching to the vocal process of the arytenoid cartilage, helps abduct the vocal folds.
John intends to produce the sound [h] while teaching it to an L2 English learner. He assumes that producing [h] requires his vocal folds to be pushed apart and also that this is accomplished by pushing the two vocal folds away by the lateral cricoarytenoid (LCA) muscles in his larynx. Is this assumption likely true or false?
False
Sarah is explaining to her phonetics class how the vocal folds behave during the production of the sound [s]. She claims that producing [s] requires the vocal folds to be tightly adducted by the posterior cricoarytenoid (PCA) muscles to prevent voicing. Is her claim likely true or false?
False
Observe the following figure and note how the liquid levels in the vertical tube differ on both sides. Now, imagine a similar scenario where the horizontal tube (indicated by arrows) has a uniform width along its entire length. Let’s assume that, in this case, the liquid levels in the vertical tube will be approximately the same. Is this assumption likely true or false?
True
Elissa is using an Electroglottograph (EGG) to study vocal fold vibration. She explains that the EGG signal strength increases when the vocal folds have greater contact and decreases when they are more separated. Is her explanation likely true or false?
True
