| Question | Answer |
|---|
| T/F: Rate of gastric emptying increases with rectal and colonic distention. | |
| enzyme important for the production of protons and bicarbonate in the parietal cell | |
| this hormone acts at the hypothalamus to suppress appetite | |
| T/F: Ghelin is released during fasting which stimulates appetite | |
| P/D1 cells release what hormone? | |
| T/F: ECL cells can be activated by acetylcholine or gastrin | |
| All stomach cell types are activated by the neurotransmitter (from the enteric nervous system) Acetylcholine, except which cell? | |
| T/F: Proton pump inhibitors bind irreversibly to the H/K proton pump. | |
| The movement of Cl into the parietal cell is coupled to the movement of which ion out of the cell? | |
| these cells produce pepsinogen and gastric lipase | |
| Cl ions are transported into the lumen of the stomach using which type of transport protein? | |
| Which histamine receptor is found on the basolateral membrane of the parietal cell? | |
| occurs due to a defiency in vitamin B12, which inhibits the body's ability to go through erythropoesis | |
| these cells produce HCl and intrinsic factor | |
| Secretin ____ (promotes or inhibits) gastric emptying | |
| 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. | |
| failure of the pyloric sphincter to relax for gastric emptying... leads to projectile vomiting | |
| these cells produce histamine | |
| T/F: Prilosec or Omeprazole acts at the basolateral membrane of the parietal cell. | |
| CCK ____ (promotes or inhibits) gastric emptying | |
| H2 blockers prevent the binding of ____ to prevent the production of acid. | |
| Peptide tyrosine-tyrosine (PYY) and glucagon like peptide (GLP1 and GLP2) ____ (stimulates/inhibits) gastric emptying | |
| occurs due to uncontrolled gastric emptying due to the lack of feedback inhibition by the duodenum and undigested food makes it to the colon | |
| Cl ions are transported into the parietal cell using which type of transport protein? | |
| Nutrients in the ileum and the colon influence gastric emptying through the _____ mechanism | |
| essential for binding and absorption of vitamin B12 | |
| These cells in the stomach are activated by the H+ions in the stomach to reduce the release of gastrin | |
| severely delayed gastric emptying or no emptying | |
