QuestionAnswer
pavlov's classical conditioning is an example of which phase of digetion?
solely serous secreting salivary gland
Aldosterone acts on salivary duct cells to increase the reabsorbtion of which two ions?
Which neurotransmitter stimulates the release of gastrin from G cells in the stomach?
this channel is involved in cycling Cl back into the lumen of the pancreatic duct
Saliva is characterized by the presence of which two molecules (ions)?
Dehydration, fear, sleep, aand anticholinergic drugs ____ (promotes... inhibits) activation of salivary glands
enzymes within salivary or exocrine glands are released in ...
this phase of digestion occurs when a stimulus from the stomach influences function of the small intestine and other portions of the GI tract.
T/F: Only parasympathetic innervation stimulates saliva production
the phase of digestion that begins in the brain. An example includes the origination of the salivary reflex at the site of food
At low flow rates, which two ions dominate pancreatic juice?
T/F: Pancreatic acinar cells are responsible for the bicarbonate secretion of the exocrine pancreas
These cells in the duodenum respond to H+ ions and release secretin in response to higher acid concetration
mucous secreting salivary gland
In the gastric and cephalic phases, the pancreatic acinar cells release zymogen granules in response to activation of muscarinic cholinergic receptors as well as receptors for whic
released by pancreatic ductal cells to neutralize the acidic chyme from the stomach
Would saliva be most plasma in high or low flow rates?
This hormone activates the CFTR channel
the major sympathetic receptor at acinar cells is ____.
bicarbonate concentration in the exocrine pancreatic juice is ____ than plasma
gland that is the main contributor to saliva (70%)
produces 5% of saliva
This enzyme is bound to the duodenal epithelial cells and activates trypsin
T/F: The composition of saliva changes with the flow rate.
These cells in the duodenum are activated mainly by fat (or amino acids) and release CCK to increase pancreatic enzyme release
QuestionAnswer
Enzyme responsible for activation of most of the pancreatic proteolytic emzymes
Which portion of the salivon primarily receives innervation for the autonomous nervous system
t/F: the submandibular gland is a mucous secreting gland.
In the intestinal phase, this hormone acts at acinar cells to cause the release of zymogen granules
T/F: Patients with cystic fibrosis can present with malabsorption and steatorrhea, due to a deficiency of pancreatic enzymes
produces 25% of saliva
this type of acinus helps to lubricate food
unit of salivary gland that is responsible for producing saliva
At high flow rates, which two ions dominate pancreatic juice?
atropine inhibits ___ receptors
T/F: Saliva is usually a hypotonic solution.
In the gastric and cephalic phases, the vagus can act to stimulate the release of bicarbonate by the duct cells. In the intestinal phase, what stimulates the release of bicarbonate
T/F: Pancreatic juice is isotonic.
Although, sympathetic innervation acts to activate salivary acinar cells, what prevents the release of saliva?
Where does protein digestion begin?
T/F: The ductal portion of the salivon acts to modify the ionic composition of saliva
T/F: In addition to GRP, amino acids and peptides can stimulate G cells to release gastrin.
atropine inhibits ____ activation of salivary ducts
this phase of digestion occurs when a stimulus from the intestine sends feedback and instructions to other portions of the GI tract
T/F: In the intestinal phase, gastrin and the vagus nerve act to stimulate zymogen granule release.
T/F: The ducts of the salivary gland are impermeable to water, while the ducts of the pancreas are permeable to water.
type of acinus that produces watery saliva that contains a amylase, lysozyme, peroxidases, and IgA
major event that occurs during the interdigestive phase
the parasympathetic nervous system cause vasodilation by using which NT?
Channel involved in taking the Cl out of the lumen of the pancreatic duct, while taking Bicarbonate from the blood into the lumen of the pancreatic duct
T/F: Saliva secretion is controlled by GI hormones.
