5 Questions
Which cell type is responsible for secreting mucus and bicarbonate ions?
Mucous cells
What is the primary source of gastric acid secretion in the stomach?
H+/K+ ATPase in the apical membrane of parietal cells
What stimulates the release of histamine from ECL cells, which in turn stimulates acid secretion?
Gastrin
What is the net result of the stimulation of ECL cells by both acetylcholine and gastrin?
Increased histamine release
Which nervous system is involved in the food-related stimulus to increase the rate of acid secretion in the stomach?
Parasympathetic and enteric nervous systems
Test your knowledge of stomach anatomy and the three cell types involved in gastric acid secretion with this quiz. Explore the functions of mucous cells, parietal cells, and enterochromaffin-like (ECL) cells, and their roles in secreting mucus, hydrochloric acid, and bicarbonate ions.
