|---|
| pespinogen and HCl are released into the lumen of the stomach... where is histamine released? | |
| these cells produce gastrin | |
| Peptide tyrosine-tyrosine (PYY) and glucagon like peptide (GLP1 and GLP2) ____ (stimulates/inhibits) gastric emptying | |
| T/F: Proton pump inhibitors bind irreversibly to the H/K proton pump. | |
| T/F: Rate of gastric emptying increases with rectal and colonic distention. | |
| 2nd messenger involved in activation of the parietal cell | |
| The gland of the stomach is known an ____ gland. | |
| occurs due to a defiency in vitamin B12, which inhibits the body's ability to go through erythropoesis | |
| Cl ions are transported into the parietal cell using which type of transport protein? | |
| 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. | |
| Hypoglycemia ___ (increase or decreases) gastric emptying. | |
| CCK ____ (promotes or inhibits) gastric emptying | |
| what activates pepsinogen? | |
| 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. | |
| made by the I cells of the duodenum | |
| T/F: Prilosec or Omeprazole acts at the basolateral membrane of the parietal cell. | |
| T/F: An increase in pH (basicity) slows gastric emptying. | |
| How does potassium get out of the parietal cell? | |
| this hormone acts on the G cell in the antrum of the stomach to inhibit the release of gastrin | |
| The movement of Cl into the parietal cell is coupled to the movement of which ion out of the cell? | |
| T/F: Tagemet and cimetidine prevent acid production by blocking H1 histamine receptors | |
| Secretin ____ (promotes or inhibits) gastric emptying | |
| P/D1 cells are located where? | |
| T/F: The parietal cell can be activated by Acetylcholine, histamine, or gastrin. | |
| Which histamine receptor is found on the basolateral membrane of the parietal cell? | |
| All stomach cell types are activated by the neurotransmitter (from the enteric nervous system) Acetylcholine, except which cell? | |
| which two products of oxidative phosphorylation are important for the production of stomach acid. | |
| H2 blockers prevent the binding of ____ to prevent the production of acid. | |
