Chapter 3 Flashcards
To create an utterance that is spontaneous or limited
Produce
The vibration of air passing between 2 vocal folds that produces sound that is used for speech
phonation
movement of air into and out of the lungs that allows for the exchange of oxygen and carbon dioxide
Respiration
The process of drawing air into the lungs
Inspiration/inhalation
The process of breathing air out of the lungs
Exhalation/expiration
The upper part of the trunk that contains the organs of respiration and circulation
Thoracic cavity
What is part of the thoracic cavity?
Thorax, rib cage, chest
Carries air down to and up from the lungs
Trachea
Firm, fibrous, and strong connective tissue that does not contain blood vessels
Cartilage
Separates the thoracic cavity from the abdominal cavity; main muscle of respiration
Diaphragm
Which direction does the diaphragm move during exhalation?
up
Which direction does the diaphragm move during inhalation?
down
Spongy tissue of the lungs where gas exchange takes place
Alveolar sacs
Structure that contains cartilages, muscles, and membranes that produce voice by air passing between the vocal folds
Larynx
Solid circle of cartilage shaped like a ring located behind the thyroid cartilage and on top of the first tracheal ring
Cricoid cartilage
Largest of the laryngeal cartilages that is the main structure of the larynx and encloses and protects the vocal folds
Thyroid cartilage
Pair of pyramid shaped cartilages that sit on top of the posterior edge of the cricoid cartilage and rotate to open and close the vocal folds and pivot to help change the pitch of voice
Arytenoid cartilage
Drops over the vocal folds to prevent food and liquid from entering into the trachea while swallowing
Epiglottis
Pair muscles that open and close rapidly to produce voice; protects the trachea and lungs from penetration of food and liquid
True vocal folds
Thick folds of mucous membranes that do not vibrate during speech but close tightly during swallowing to prevent material from entering the trachea
False vocal folds
The opening of the vocal folds
Abduct
The closing of vocal folds
Adduction
When air flowing through a tube reaches a constriction, there is a speed of flow of air that causes decreased person on the walls of the constriction that results in a slight negative pressure at the constriction
Beroulli’s law
The number of complete cycles per second that the vocal folds vibrate
Frequency
The unit of vibration adopted internationally to replace cycles per second
Hertz
The force with which the vocal folds open and close and the amount of air that escapes between the open vocal folds
Intensity
