| Question | Answer |
|---|
| pespinogen and HCl are released into the lumen of the stomach... where is histamine released? | |
| Secretin ____ (promotes or inhibits) gastric emptying | |
| Peptide tyrosine-tyrosine (PYY) and glucagon like peptide (GLP1 and GLP2) ____ (stimulates/inhibits) gastric emptying | |
| leptin is release by which type of tissue? | |
| The movement of Cl into the parietal cell is coupled to the movement of which ion out of the cell? | |
| responsible for getting H+ ions into the lumen of the stomach | |
| T/F: Ghelin is released during fasting which stimulates appetite | |
| P/D1 cells are located where? | |
| 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. | |
| enzyme important for the production of protons and bicarbonate in the parietal cell | |
| Which histamine receptor is found on the basolateral membrane of the parietal cell? | |
| made by the I cells of the duodenum | |
| T/F: Ileal fat increase gastric emptying. | |
| T/F: ECL cells can be activated by acetylcholine or gastrin | |
| failure of the pyloric sphincter to relax for gastric emptying... leads to projectile vomiting | |
| These cells in the stomach are activated by the H+ions in the stomach to reduce the release of gastrin | |
| Cl ions are transported into the parietal cell using which type of transport protein? | |
| T/F: An increase in pH (basicity) slows gastric emptying. | |
| 2 causes of peptic ulcers | |
| H2 blockers prevent the binding of ____ to prevent the production of acid. | |
| T/F: Proton pump inhibitors bind irreversibly to the H/K proton pump. | |
| these cells produce gastrin | |
| 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. | |
| All stomach cell types are activated by the neurotransmitter (from the enteric nervous system) Acetylcholine, except which cell? | |
| The gland of the stomach is known an ____ gland. | |
| ___ are hormones released by the duodenum and cause feedback on stomach to decrease gastric emptying and secretions | |
| Nutrients in the ileum and the colon influence gastric emptying through the _____ mechanism | |
| CCK ____ (promotes or inhibits) gastric emptying | |
