respiratory system
organs and other body parts involved in the breathing process, exchange of oxygen and carbon dioxide.
laryngeal system
larynx (air valve) prevents objects from entering the trachea and lungs. also is responsible for speech production (voice box)
articulatory/resonating system
opening of the mouth - the vocal folds; comprises the oral, nasal, and pharyngeal cavities, and forms the vocal tract.
resting tidal breathiing
inhalation & exhalation during restful breathing
alveolar pressure
pressure within the lungs
larynx
an air valve, composed of cartilages, muscles, and other tissues. it is the principal sound generation for speech production; voice box.
hyoid bone
horse-shoe shaped structure that suspends the larynx and serves as the point of attachment for both laryngeal and tongue musculature.
thyroid cartilage
largest larynx cartilage, sits beneath the hyoid bone
thyroid prominence
adam’s apple (jutting protrusion out of the neck, just below the thyroid notch).
glottis
space between the vocal folds
vocal fold adduction
moving together, accomplished by contraction of the lateral cricoarytenoid & arytenoid (transverse & oblique muscles).
vocal fold abduction
(moving apart) done by the posterior cricoarytenoid.
uvula
termination of the velum
