🧠 2️⃣ Mnemonics
Mnemonic Title:
Functions of CCK
Mnemonic Word:
“CCK = Contracts, Churns, Keeps stomach slow”
Meaning:
- Contracts gallbladder
- Churns out pancreatic enzymes
- Keeps gastric emptying slow
Mnemonic Title:
Functions of Secretin
Mnemonic Word:
“Secretin Saves Small intestine”
Meaning:
- Stimulates bicarbonate secretion
- Protects duodenum from acid
Mnemonic Title:
Major Intestinal Movements
Mnemonic Word:
“SP Moves Gut”
Meaning:
- S = Segmentation → mixing
- P = Peristalsis → propulsion
📋 3️⃣ Memory Tables
Table 1 — Segmentation vs Peristalsis
| Feature | Segmentation | Peristalsis |
|---|---|---|
| Main Function | Mixing | Propulsion |
| Direction | Local | Forward |
| Muscle Action | Circular contractions | Wave-like contractions |
| Role in Digestion | Mixes chyme | Moves chyme |
Table 2 — GI Hormones
| Hormone | Main Stimulus | Main Function |
|---|---|---|
| Gastrin | Protein in stomach | ↑ Gastric acid |
| Secretin | Acid in duodenum | ↑ Bicarbonate |
| CCK | Fat and proteins | ↑ Pancreatic enzymes |
| Motilin | Fasting | Migrating motor complex |
⚡ 4️⃣ Rapid Revision Points
Must Remember:
• Segmentation mixes; peristalsis propels.
• Myenteric plexus controls motility.
• Submucosal plexus controls secretion.
• Brunner’s glands secrete alkaline mucus.
• Crypts of Lieberkühn secrete intestinal fluid.
• Secretin stimulates bicarbonate secretion.
• CCK stimulates pancreatic enzyme release.
• Lactase is a brush border enzyme.
• Pancreatic lipase deficiency causes steatorrhea.
• Villous atrophy causes malabsorption.
• Motilin regulates migrating motor complex.
