ENT · Larynx and airway: myoelastic aerodynamic theory

Sample item

Which theory explains phonation as vocal fold closure, followed by rising subglottic pressure that blows the folds apart, then elastic recoil and the Bernoulli effect closing them again?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

C. Myoelastic-aerodynamic theory

In the myoelastic-aerodynamic theory, adducted cords resist expiratory airflow, subglottic pressure builds and opens them, and elastic recoil plus the Bernoulli effect pull them together, repeating each cycle. The neurochronaxic theory is outdated. The place theory concerns hearing.

Option by option

  • A. Gate control theory

    Gate control theory concerns pain.

  • B. Place theory

    The place theory describes frequency coding in the cochlea.

  • C. Myoelastic-aerodynamic theory (correct)

    Correct. This is the accepted theory of voice production.

  • D. Neurochronaxic theory

    The neurochronaxic theory proposed that each cycle is nerve driven and is disproved.
