Exam 1 Part 2 Flashcards
Lower air pressure = ______
Inhalation
Higher air pressure = ______
Exhalation
Diaphragm contracts and lowers, ribcage slightly raises and expands, brainstem helps with this process
Quiet inspiration
What happens to the volume inside of the thoracic cavity during quiet inspiration?
Increases
Process that includes the alveolar sacs relax, thoracic cavity relaxes, air pressure increases, air is forced out of the lungs, up the trachea, vocal folds open, out of the nose or mouth
Quiet expiration
Contains cartilage, muscles, and membranes that produces voice by air passing between the vocal folds
Larynx
Where is the larynx located?
Top of the trachea
Largest laryngeal cartilage; the main structure of the larynx that encloses and protects the vocal folds
Thyroid cartilage
Referred to as the Adam’s apple
Anterior point/laryngeal prominence
Space between vocal folds when abducted
Glottis
Look pearly white, point of “V” is anterior
True vocal folds
Are the vocal folds abducted or adducted during voicing?
Adducted
Vocal folds important for preventing food getting below the true vocal folds
False vocal folds
In normal phonation, false folds remain in _____ position
Open
What happens during phonation?
Brain tells true vocal folds to adduct, tells us to exhale, air pressure below vocal folds build up, vocal folds blow open with anterior and posterior areas closed
