What do enterochromaffin-like (ECL) cells, which can be found in the gastric mucosa, secrete? Gastric Inhibitory Peptide Gastrin Hydrogen ions (H+) Pepsinogen Histamine Please select an option Incorrect. Gastric Inhibitory Peptide is secreted by K cells in the mucosa of the jejunum and duodenum. It acts to inhibit gastric motility and hydrochloric acid secretion in the stomach and induce insulin secretion. Enterochromaffin-like cells secrete histamine. WikiVet Article: Forestomach Incorrect. Gastrin is secreted by G-cells in the pyloric mucosa which stimulates enterochromaffin-like cells to secrete histamine. WikiVet Article: Forestomach Incorrect. Hydrogen ions are secreted by parietal cells in the gastric mucosa to decrease the pH in the stomach lumen which causes denaturation of ingested proteins. Enterochromaffin-like cells secrete histamine. WikiVet Article: Forestomach Incorrect. Pepsinogen is secreted by chief cells in the gastric glands which is converted to its active form pepsin by hydrochloric acid in the gastric lumen.Enterochromaffin-like cells secrete histamine. WikiVet Article: Forestomach Correct! Enterochromaffin-like cells secrete histamine which stimulates parietal cells to secrete hydrogen ions. WikiVet Article: Forestomach

The falciform ligament forms between which two structures? The lesser curvature of the stomach and the liver The spleen and the liver The stomach and the spleen The kidney and the spleen The liver and the body wall Please select an option Incorrect. The liver forms in the ventral mesentery. The liver remains attached to the stomach by persisting ventral mesentery known as lesser omentum and to the body wall by ventral mesentery known as the falciform ligament.

Which of the following organs is considered to be retroperitoneal? Pancreas Liver Kidneys Duodenum Spleen Please select an option Incorrect. The pancreas is enclosed by a fold of visceral peritoneum so is intraperitoneal. The kidneys are located between the parietal peritoneum and the body wall, hence they are considered retroperitoneal. In practice, this means that the kidneys (and associated structures such as adrenal glands and ovaries) can be easily visualised at exploratory surgery by performing either a duodenal manoeuvre (for the right kidney) or colic manoeuvre (for the left kidney). The duodenal manoeuvre involves lifting the descending duodenum up, and moving it gently across the abdominal cavity to the left side of the body. This causes the mesoduodenum to catch the abdominal viscera and pull them to the left, allowing the right retroperitoneal space to be seen. The colic manoeuvre uses the descending colon and mesocolon similarly to see the left retroperitoneal space. WikiVet Article: Retroperitoneal organs Incorrect.
