SB82 GI Hormones ABSITE review
| Question | Answer |
|---|---|
| Hormone produced by G cells in the antrum ______ | Gastrin |
| Target cells of gastrin are _____ cells and _____ cells | Chief parietal |
| Response to gastrin is increased ________________ (3) | HCl, intrinsic factor, pepsinogen |
| Hormone produced by D cells in the antrum ____ | Somatostatin |
| Secretion of somatostatin is stimulated by _____ in the ______ | Acid, duodenum |
| Substance used to decrease pancreatic fistula output _________ | Octreotide |
| Hormone produced by K cells in the duodenum _______ | GIP |
| Target cells of GIP | Parietal cells (decreased acid and pepsin secretion) and beta cells of pancreas (increased insulin release) |
| Hormone produced by I cells of the duodenum and jejunum _______ | Cholecystokinin |
| Secretion of CCK is stimulated by ________ and _______ | Amino acids, fatty acid chains |
| Response to CCK | Gallblader contraction, relaxation of the sphincter of Oddi, increased pancreatic enzyme secretion, increased intestinal motility |
| Hormone produced by S cells of duodenum _____ | Secretin |
| Secretion of secretin is stimulated by ______ | Fat, bile, low pH |
| Secretion of secretin is inhibited by ______ | pH > 4.0, gastrin |
| Response to secretin | Increased pancreatic bicarbonate, increased bile flow, inhibition of gastrin, inibition of HCl release |
| VIP is produced by cells in _____ and _______ | Gut, pancreas |
| Secretion of VIP is stimulated by fat and _________ | Acetylcholine |
| Reponse to VIP | Increased intestinal secretion and motility |
| VIP inhibits release of ______ | Gastrin |
| Insulin secretion is stimulated by glucose, glucagon, and ________ | CCK |
| Secretion of insulin is inhibited by ___________ and _______ | somatostatin, pancreatostatin |
| Glucagon is stimulated by the ______ cells of the pancreas | Alpha |
| Hormone secreted by islet cells in the pancreas _____ | Pancreatic polypeptide |
| Secretion of pancreatic polypeptide is stimulated by ______ | Food, vagal stimulation, other GI hormones |
| Response to pancreatic polypeptide _________ | Decreased pancreatic and gallbladder secretion |
| Hormone that is released by intestinal cells that increases intestinal motility _____ | Motilin |
| Medication that acts at the motilin receptor to decrease intestinal motility ________ | Erythromycin |
| A hormone, also known as gastrin-releasing peptide, that also increases intestinal motor activity and pancreatic enzyme secretion ________ | Bombesin |
| Hormone that is released from the terminal ileum following a fatty meal ____ | Peptide YY |
| Response to peptide YY | Inhibits acid secretion, stomach contraction, gallbladder contraction, pancreatic secretion |
| Anorexia is mediated by this brain structure _____ | Hypothalamus |
