    Study Notes

    Power Mechanism of the Respiratory Tract

    • The power mechanism of the respiratory tract is responsible for generating airflow.

    The Glottis

    • The glottis is the opening between the vocal folds in the larynx.
    • It lies between the supra-glottal cavities and the subglottal system.
    • The glottis plays a crucial role in respiration by regulating airflow.
    • During breathing, the glottis is open allowing for free flow of air.
    • During speech production, the glottis can be adjusted by the vocal folds to regulate airflow.

    Supra-Glottal Cavities

    • The supra-glottal cavities are the spaces above the glottis that include the pharynx and the nasal cavity.
    • They influence the acoustic characteristics of voice and speech.
    • The supra-glottal cavities help to modify the resonance of the voice.

    Power Mechanism Components

    • The power mechanism is made up of the lungs, diaphragm, chest muscles, abdominal muscles, and the subglottal system (trachea, bronchi, and alveoli).
    • These structures work together to generate airflow and pressure for breathing and speech.
