Complete Mnemonic Collection for HP-05

1. Total Bone Count: "206"

• "Two Oh Six = 206" — just memorize directly; then: 80 axial + 126 appendicular = 206

2. Axial Skeleton Components: "SVRSH = 80"

• Skull (22) + Vertebrae (26) + Ribs (24) + Sternum (1) + Hyoid (1) = 80
• Full sentence: "Some Very Rare Specimens Have" 22 + 26 + 24 + 1 + 1 = 80

3. Vertebral Formula: "Charlie Tried Lifting Stones Carefully"

• Cervical (7) + Thoracic (12) + Lumbar (5) + Sacrum (5→1) + Coccyx (4→1)
• Or just: 7-12-5 for C-T-L (the unfused three), then +2 fused bones = 26 total

4. Sarcomere Bands During Contraction: "A STAYS, I & H STRAY"

• A band stays constant
• I band and H zone stray $\frac{decrease}{disappear}$
• Full version: "A is Always constant; I Decrease; H zone Has gone (disappears at max contraction)"

5. Six Synovial Joints: "Happy People Ball Glide Sideways Easily"

• Hinge + Pivot + Ball-and-socket + Gliding + Saddle + Ellipsoid

6. Synovial Joint Examples (each): "KEAS-TH WSS"

• Knee/Elbow (Hinge), Atlas-Axis (Pivot), Shoulder/Hip (Ball-and-socket), InterTarsal/carpal (Gliding), THumb CMC (Saddle), Wrist (Ellipsoid)

7. Cross-Bridge Cycle: "CATCHER"

• Calcium released from SR
• Actin binding sites exposed (tropomyosin shifts)
• Tight binding (cross-bridge forms)
• Cross-bridge Causes power stroke
• Held (rigor state) until ATP binds
• Ejection (ATP binds → myosin detaches)
• Recycle (ATP hydrolysis re-energizes head)

8. Muscle Type Memory: "CSI"

• Cardiac = striated + involuntary (the odd one out — breaks the pattern)
• Skeletal = striated + voluntary
• Involuntary non-striated = smooth

9. Disorders Memory: "MOST GAR"

• Myasthenia gravis — autoimmune ACh receptor destruction
• Osteoporosis — low bone density, post-menopausal women
• Skeletal dystrophy (Muscular) — genetic dystrophin
• Tetany — hypocalcemia
• Gout — uric acid crystals, big toe
• Arthritis rheumatoid — autoimmune synovial membrane
• Rheumatoid differs from osteoarthritis (degenerative)

10. H Zone vs Z-line (what's bisected by what): "Z bisects I; M bisects H"

• Z-line bisects the I band (Z cuts I)
• M-line bisects the H zone (M marks the middle of H)
