Week 2 Vocab Flashcards
What are the 4 systems involved in speech?
Respiratory
Phonatory
Resonatory
Articulatory
In speech, to create an utterance (sound, syllable, word, sentence, or longer) that is spontaneous or imitated.
Produce
Phonation
The vibration of air passing between the two vocal folds that produces sound that is used for speech.
Respiration
The movement of air into/out of the lungs that allows for the exchange of oxygen and CO2
Inspiration (inhalation)
The process of drawing air into the lungs.
Expiration (exhalation)
The process of breathing air out of the lungs.
Overlaid function
Function not necessary to sustain life.
What parts of the body provides protection and framework for the respiratory system?
Rib cage
Sternum/breastbone
Thoracic cavity (thorax)
The upper part of the trunk that contains the organs of respiration (lungs) and circulation (heart); extends from the clavicle to the 12th rib.
T/F: The bones of the thoracic cavity, including the pelvis, provide attachments for the many muscles involved in phonatory system.
FALSE
Respiratory system
Trachea (windpipe)
The tube that begins just below the larynx and continues down to where it divides into the lungs; about 4-5 inches long, 1 inch in diameter.
T/F: The trachea consists of about 20 rings made of cartilage.
TRUE
Cartilage
Firm, fibrous, strong connective tissue that does not contain blood vessels.
T/F: 18 pairs of muscles are involved in the processes of inspiration and expiration.
FALSE
26 pairs of muscles
Diaphragm
Dome-shaped muscle that separates the thoracic and abdominal cavities; main muscle of respiration.
Which abdominal organ and their muscles aid in forced exhalation?
The stomach and the muscles over it.
Process of Respiration
- Respiratory center in brainstem sends msgs to muscles for inhalation.
- The diaphragm contracts/lowers, ribcage raises/expands.
- Volume inside thoracic cavity increases, decrease of air pressure in lungs.
- Difference in environmental air pressure and pressure inside lungs cause air from outside to flow through nose and down trachea into lungs to equalize air pressure, causing inhalation.
Alveolar sacs
Spongy tissue of the lungs where gas exchange takes place; walls are once cell thick/porous allowing rapid transfer of fresh O2/CO2.
The respiratory center of the brain is in the.. ?
Brainstem
Larynx (voice box)
The structure that contains cartilages, muscles, and membranes, that produce voice by air passing between the vocal folds that is located at the top of the trachea.
Name two aspects that make the anatomy/physiology of the larynx so simple.
The structures of the larynx are stacked on top of one another; the various muscles inside/outside can only contract/relax.
Name two aspects of anatomy/physiology of the larynx that make it complex.
The structures can move in subtle ways that alter loudness, pitch, and quality of voice; precises combination and amounts of muscle contraction/relaxation can provide pure, grating, strident voices of some people.
Where is the larynx located?
Between the top of the trachea and just below the hyoid bone that helps support it.
Thyroid cartilage (Adam’s apple)
The main structure of the larynx; encloses/protects the vocal folds.
