The Larynx and Vegetative Functions Quiz

The nonspeech laryngeal function of the larynx includes its role in protective function of the airway. Coughing is a violent reflexive action which requires abduction of the vocal folds, deep inhalation, tensing and adducting the vocal folds, elevation of the larynx, and high subglottal pressure. The advantage of coughing is that it functions as a safety mechanism to expel irritants, but the disadvantage is that the force required for its production leads to chronic irritation and vocal abuse.

Throat clearing is useful to clear the airway.

The larynx has a vegetative function in the respiratory system pathway and serves as a protective mechanism for the airway during swallowing. It closes up to keep things away from the airway and helps to fix thoracic structures for activities that require abdominal pressure, such as bowel movement, lifting weight, and giving birth. During these activities, the vocal folds are approximated.

<p>The larynx has vegetative functions as part of the respiratory system pathway, serving as a protective mechanism for the airway. It closes during swallowing and helps fix thoracic structures for activities requiring abdominal pressure. It also plays a role in non-speech laryngeal functions, such as protective airway functions like coughing and throat clearing.</p> Signup and view all the answers

<p>Coughing serves as a protective function of the airway, requiring the vocal folds to first abduct, followed by deep inhalation, tensing and adducting the vocal folds, elevation of the larynx, and the build-up of high subglottal pressure under the vocal folds. Its advantage is being a safety mechanism to expel irritants, but its disadvantage is that the force required for its production can lead to chronic irritation and vocal abuse.</p> Signup and view all the answers
