True
What is largest laryngeal cavity?
Thyroid cartilage
T/F the vocal folds are located between the thyroid and cricoid cartilage

True
T/F alveolar pressure is at its lowest during the peak of inspiration
True
What is the Epiglottis?
an elastic cartilage that resembles a large spoon or leaf and is located above the glottis

Decreases
T/F conversational speech uses less lung volume than passive breathing
False
T/F the biological function of the larynx is to create sound
false the biological function is to protect the lower airway by preventing food and foreign particles from entering the trachea
What is the only bone in the body that is not connected to any other bones?
the hyoid bone
What does the U-tube manomenter measure?
measures the respiration pressure
What does the spirometer measure?
measures respiratory volume
T/F the hyoid bone is a U shaped bone that sits above the thyroid cartilage
True
How many layers of tissue do the vocal folds have?
5 layers
T/F the hyoid bone loosely articulates with the thyroid cartilage
true
What is the amount of air a person exhales after tidal respiration
expiratory reserve volume
What is subglottal pressure?
the air pressure below the vocal folds, in the trachea
T/F conversational speech uses 10-15% of vital capacity when speaking
False- conversational speech uses 35-60%
What cartilage sits on the apex of each arytenoid cartilage
Corniculate
What is the amount of air remaining in the lungs after maximum exhalation
residual volume
T/F the larynx protects the lower respiratory tract
true
What is the thyroid cartilage superior to?
the cricoid
What does the circothyroid join together?
Cricoid and thyroid
What is intraoral
the air pressure inside the oral cavity
What does one cycle of respiration consists of?
1 inspiration and 1 expiration
Where does phonation happen?
the larynx
What does the epiglottis look like
a small, leaf-shaped flap of cartilage
What does the cricoid cartilage look like?
a signet ring
T/F we always talk during inhalation
false we always talk on exhalation
What is the amount of air that can be forcefully exhaled after a normal tidal volume exhalation?
Expiratory reserve volume
T/F the larynx, is composed of cartilages, muscles, ligaments, and mucous membrane
True
What is the average amount of respiratoin cycles per minute for adults?
12-18
What is the amount of air remaining in the lungs after maximum exhalation
residual volume

sternocleidomastoid and scalenes
For conversational speech, what does the subglottal pressure have to be?
7-10 cm H2O
How many liters of air does a person process every minute?
6-8 liters
T/F the deeper layers of the vocal folds are more elastic than the superficial layers.
False the deeper layers in the vocal folds are thicker and made from collagen or muscle
T/F the primary expiratory muscle is the diaphragm
false the diaphragm is the primary muscle of inspiratory
What does Inspiratory Capacity include
tidal volume and inspiratory reserve volume
T/F the vital capacity is the amount of air you can breathe after max inhalation
True
What is the larynx suspended by?
hyoid bone
What is the space between the two vocal folds
the glottis
What is the maximum inspiration after tidal expiration
inspiratory capacity
What happens after moving the thyroid forward by the cricothyroid?
stretches/ lengthens the vocal folds

epithelial, superficial lamina properia, intermediate lamina properia, deep lamina properia, and Thyroarytenoid muscle
T/F a muscle of forced expiration is the internal intercostal muscle
true
