Chapter 8 Flashcards
A lip seal is important because
it keeps food and liquids in mouth during mastication & it helps maintain the positive pressure for swallowing (A&B)
Stroking the check of a neonate will result in
the infant orienting to the side of stimulation
The process of preparing food for swallowing is termed
mastication
The adult pharynx
serves as a passageway for both food and air
The term meaning disorders of swallowing is
dysphagia
Which of the statements is not true?
Infant tongue is smaller than an adults
Infants larynx is elevated relative to an adult
Infant velum makes contact with the epiglottis
All of the above
The term “bolus” refers
to the mass of food being prepared for swallowing
Which of the following is not considered part of mastication?
Passing the bolus into the pharynx
The taste from the anterior two thirds of the tongue is mediated by the _____ cranial nerve.
VII facial
The taste from the epiglottis and esophagus is mediated by the ______ cranial nerve.
X vagus
Taste from bitterness is by ________ cranial nerve
IX glossopharyngeal
Taste from sweet/saltiness and sourness is by _______ cranial nerve
VII facial
Which of the following is not part of mastication?
passing the bolus into the pharynx
The process of swallowing is termed
deglutition
The important function of the buccal musculature in mastication and deglutition is
keeping food or liquid out of the buccal cavity & keeping food or liquid on the molars for chewing.
Velar closure during the swallow is important because
it keeps one from having nasal regurgitation (return of food upwards) & it provides a seal for the positive pressure of swallowing
The bolus moves down the pharynx by means of
increased pharyngeal pressure & pharyngeal peristalsis
Soft contact with the inner margin of the lips of a newborn will result in
protrusion and retraction of the tongue
elevation and depression of the mandible
The sucking reflex includes
pumping the tongue forward and back repeatedly
elevation and depression of the mandible
swallow of bolus after four or five pumps of the tongue
In an infant, the epiglottis
remains elevated during swallowing & remains in contact with the velum during the swallow
An infant can
breathe and swallow at the same time
The adult swallowing pattern includes
elevation of the larynx
elevation of the velum
closing of the epiglottis
