📋 3️⃣ Memory Tables
Commonly Confused Gastric Cells
| Cell Type | Main Secretion | Main Function |
|---|---|---|
| Parietal cell | HCl + Intrinsic factor | Acid production + B₁₂ absorption |
| Chief cell | Pepsinogen | Protein digestion |
| Mucous cell | Mucus + bicarbonate | Mucosal protection |
| G cell | Gastrin | Stimulates acid secretion |
| ECL cell | Histamine | Enhances acid release |
⚡ 4️⃣ Rapid Revision Points
(Last-Minute Revision)
Must Remember:
• Gastric juice pH is approximately 1–3
• Parietal cells contain many mitochondria
• Proton pump is final step in acid secretion
• Gastrin stimulates parietal cells
• Histamine acts via H₂ receptors
• Somatostatin inhibits acid secretion
• Intrinsic factor is essential for Vitamin B₁₂ absorption
• Bicarbonate entry into blood causes alkaline tide
• Mucus barrier protects gastric mucosa
• Excess acid leads to ulcer formation
🩺 5️⃣ Clinical Memory Hooks
Clinical Hook 1:
Peptic ulcer → Excess acid secretion → Epigastric burning pain
Clinical Hook 2:
Autoimmune gastritis → Loss of intrinsic factor → Pernicious anemia
Clinical Hook 3:
NSAID use → Reduced mucus protection → Gastric ulcer risk
Clinical Hook 4:
Proton pump inhibition → Reduced H⁺ secretion → Ulcer healing
