Pharyngeal wall movement during speech

S Niimi

    |January 1, 1981
    PubMed
    Summary
    This summary is machine-generated.

    The epipharyngeal wall aids velopharyngeal closure, while the mesopharyngeal wall assists vowel articulation during speech. Muscle activity, particularly the levator veli palatini and superior constrictor, drives these distinct pharyngeal wall movements.

    Area of Science:

    • Speech science
    • Anatomy
    • Physiology

    Background:

    • Understanding pharyngeal wall function is crucial for speech production.
    • Differentiating roles of mesopharynx and epipharynx in articulation is key.

    Purpose of the Study:

    • To investigate functional differences between mesopharynx and epipharynx lateral walls during speech.
    • To correlate pharyngeal wall movements with specific muscle activities.

    Main Methods:

    • Utilized endoscopic techniques to visualize pharyngeal wall movement.
    • Employed electromyography to record muscle activity during speech tasks.

    Main Results:

    • Epipharyngeal wall movement contributes to velopharyngeal closure.

  • Mesopharyngeal wall movement is associated with vowel articulation.
  • Levator veli palatini muscle activity correlates with epipharyngeal wall and velum movement.
  • Superior constrictor muscle activity is linked to mesopharyngeal wall medial displacement.

    • Conclusions:

    • Distinct functional roles exist for the mesopharynx and epipharynx in speech.
    • Specific muscles, levator veli palatini and superior constrictor, are responsible for observed pharyngeal wall movements.
