Chewing and Swallowing Flashcards
In the pharyngeal phase of swallowing, the epiglottis covers the to prevent food from entering the trachea.
Larynx
Breathing (continues/stops) during the pharyngeal phase of swallowing.
Stops
The voluntary act of swallowing is initiated in the
Mouth
The swallowing center located in the controls the involuntary actions of swallowing.
Medulla Oblongata
Chewing mixes ingested carbohydrates with salivary (enzyme) to initiate carbohydrate digestion.
Amylase
Information from the medullary swallowing center is directed to the striated muscles of the
pharynx and upper
striaed muscles of pharynx
upper esophagus
The involuntary component of chewing is initiated when the of the stretch reflexes in the mouth detect food.
mechanoreceptors
The esophageal phase of swallowing is (voluntary/involuntary) .
Involuntary
The voluntary component of chewing (can/cannot) override involuntary chewing at any time.
CAN
During the pharyngeal phase of swallowing, the (lower/upper) esophageal sphincter relaxes to allow food to pass from the pharynx to the esophagus
Upper
The (upper/lower) esophageal sphincter closes during the esophageal phase of swallowing so that food does not regurgitate into the pharynx.
Upper
The pharyngeal phase of swallowing is (voluntary/involuntary) .
Involuntary
The oral phase of swallowing is (voluntary/involuntary) .
Voluntary
Chewing mixes food with , which acts as a food softener and swallowing lubricant.
Saliva
During the pharyngeal phase of swallowing, the soft palate is pulled upward so that food cannot reflux into the .
Nasopharynx
