Swallowing and Respiration

Question 1

Speech swallowing and respiration are overlaid ?
airway protection is ?
at all times aerodigestive tract’s primary function is that of
-virtually impossible to ?

Answer 1

functions of aerodigestive tract

critical during swallow

sustaining life through oxygenation

breath and swallow at the same time

Question 2

Breathing and swallowing processes are closely ?

many muscles and structures have ?

neural control centers responsible for coordination of breathing and swallowing are contained in

cortical structures also play an important role in

Answer 2

interrelated in their central control and are highly coordinated

dual roles in respiration and swallowing

dorsomedial and ventrolateral medullary regions of the brainstem

facilitating and modulating the coordination of breathing and swallowing

Question 3

Sequence of respiration/swallow

as pharyngeal phase of swallow is initiated the ? begins
-this is called ?
-less than a
the pause in breathing is due to ? and not simply due to

swallowing typically happens during

• we swallow after some
• swallow during
• then

Answer 3

central inhibition of the respiratory muscles begins

• apneic period of swallow
• sec
• inhibition of respiration at neural control centers in the brainstem / closure of upper airways/VCs

-expiration
-amount of exhalation
-apneic period
continue to exhale

Question 4

Abnormal Sequencing:
the sequence of respiratory acts and swallowing may differ in ?
-although sequence may differ dependent on ? all research states that maximal airway protection comes when:
-… occurs
-larynx is
-laryngeal?

Answer 4

pop. with respiratory deficits
- etiology or respiratory health/disease

• expiration occurs before and after swallow
• farthest from pharynx during swallow
• cough reflex in tact

Question 5

Cough: 
stimulation of ? initiate ?
-diaphragm 
-vocal folds 
-respiratory muscles 
-pressure further increased by ?
effectiveness is measured on how much ?

Answer 5

mucosal water receptors in supralaryngeal region/ cough reflex

• contracts strongly to draw in air
• adducted
• forcefully contract (increased subglottal pressure)
• narrowing of bronchi in lungs
• subglottal pressure can be generated and how tightly VFs can be adducted
