D LUCK!I The next block of questions focuses on acid and enzyme production in the stomach. For these questions, select from: a) Parietal cells b) Chief cells c) Enterochromaffin-like cells d) D cells e) G cells 12) Chemoreceptors on sensory neurons detect biomolecules entering the stomach and then directly stimulate these cells permits Vitamin B12 absorption. release somatostatin which turns off the production of 13) These cells release a molecule called intrinsic factor that 14) A rise in H levels in the stomach stimulatesto gastric secretions.Explanation / Answer
12. e. G cells
G cells are found in the antrum of stomach and secrete gastrin. These cells are stimulated by vagal stimulation and small peptides. Inhibited by stomatostatin and involved in sensing the taste of the lumen contents
13. a. Parietal cells
Parietal cells are found in body / fundus of stomach. They secrete HCl and intrinsic factor which is essential for Vitamin b12 absorption. It is stimulated by gastrin, Acetylcholine and histamine
14. d. D cells
