Question | Answer |
CCK ____ (promotes or inhibits) gastric emptying | |
leptin is release by which type of tissue? | |
T/F: Prilosec or Omeprazole acts at the basolateral membrane of the parietal cell. | |
T/F: Ghelin is released during fasting which stimulates appetite | |
Cl ions are transported into the lumen of the stomach using which type of transport protein? | |
2 causes of peptic ulcers | |
T/F: Rate of gastric emptying increases with rectal and colonic distention. | |
T/F: The stomach is the major site for digestion. | |
these cells produce HCl and intrinsic factor | |
The superficial epithelial cells along with which other cell type in the stomach act to lubricate and protect the stomach wall? | |
This type of drug inhibits prostaglandin related defense mechanisms within the stomach | |
T/F: In some cases of peptic ulcer disease, acid from the stomach erodes the D cells of the stomach preventing the brake mechanism for acid production. | |
T/F: Proton pump inhibitors bind irreversibly to the H/K proton pump. | |
T/F: After a large meal, the alkaline tide (removal of bicarbonate from the parietal cell) causes an increase in the pH of the blood. | |
Nutrients in the ileum and the colon influence gastric emptying through the _____ mechanism | |
2nd messenger involved in activation of the parietal cell | |
These cells in the stomach are activated by the H+ions in the stomach to reduce the release of gastrin | |
made by the I cells of the duodenum | |
The gland of the stomach is known an ____ gland. | |
made by the S cells of the duodenum | |
___ are hormones released by the duodenum and cause feedback on stomach to decrease gastric emptying and secretions | |
T/F: Large volumes in the stomach increase gastric emptying | |
All stomach cell types are activated by the neurotransmitter (from the enteric nervous system) Acetylcholine, except which cell? | |
this hormone acts on the G cell in the antrum of the stomach to inhibit the release of gastrin | |
P/D1 cells are located where? | |
Peptide tyrosine-tyrosine (PYY) and glucagon like peptide (GLP1 and GLP2) ____ (stimulates/inhibits) gastric emptying | |
what activates pepsinogen? | |
