Concept #1: Anatomy of the Stomach

Concept #2: Parietal Cells and Gastric Acid

Concept #3: Chief Cells and Pepsinogen

Concept #4: Regulation of Secretion-- G Cells and ECL Cells

Concept #5: Regulation of Secretion-- D Cells and the Autonomic Nervous System

Practice: An undergraduate working in a physiology lab takes a sample of rat stomach and stains it with a marker that binds to pepsinogen. Which of the following cell types will be marked by this stain?

Practice: Omeprazole (Prilosec®) is a “proton pump inhibitor,” which means it blocks the H+/K+ ATPase. Which of the following correctly identifies both the cell type targeted by omeprazole and omeprazole’s expected effect on stomach pH?

Practice: Ranitidine (Zantac®) is a histamine receptor (H2 receptor) blocker. Which of the following correctly identifies both the cell type targeted by ranitidine and ranitidine’s expected effect on stomach pH?
