📋 3️⃣ Memory Tables
Table 1 — Cardiac vs Skeletal vs Smooth Muscle
| Feature | Cardiac Muscle | Skeletal Muscle | Smooth Muscle |
|---|---|---|---|
| Striations | Present | Present | Absent |
| Shape | Branched | Cylindrical | Spindle-shaped |
| Nuclei | Central | Peripheral | Central |
| Intercalated discs | Present | Absent | Absent |
| Control | Involuntary | Voluntary | Involuntary |
Table 2 — Heart Wall Layers
| Layer | Main Component | Main Function |
|---|---|---|
| Endocardium | Endothelium | Smooth blood flow |
| Myocardium | Cardiac muscle | Pumping action |
| Epicardium | Fat + vessels | Protection & nourishment |
⚡ 4️⃣ Rapid Revision Points
Must Remember:
• Apex of heart → Left ventricle
• Base of heart → Mainly left atrium
• Right ventricle forms most anterior surface
• Pulmonary trunk arises from right ventricle
• Aorta arises from left ventricle
• Cardiac muscle cells are branched
• Intercalated discs connect cardiac cells
• Gap junctions allow electrical continuity
• Desmosomes provide mechanical strength
• Long refractory period prevents tetany
• Myocardium is thickest in left ventricle
• Cardiac muscle is involuntary but striated
🩺 5️⃣ Clinical Memory Hooks
Clinical Hook:
Myocardial infarction → damaged myocardium → weak contraction
Clinical Hook:
Arrhythmia → impaired conductivity → irregular heartbeat
Clinical Hook:
Valve disease → disturbed blood flow → murmur formation
Clinical Hook:
Hypertension → left ventricular hypertrophy → thick myocardium
Clinical Hook:
Coronary artery blockage → ischemia → chest pain
