[Verse 1]
Femur's the giant, the thighbone king,
Humerus swings the arm like a sling,
Phalanges are tiny levers at your fingertip,
Longer than wide, built for leverage and grip,
A seesaw of calcium, a rod, not a block,
When these bones break they don't just stop—
They spiral like a barber's pole, twisting askew,
That corkscrew fracture tells the shape it grew from too.
[Chorus]
Long bones lever, short bones stack,
Flat bones armor your chest and back,
Irregular twists where the puzzle bends,
Sesamoid hides where a tendon ends,
Five shapes building one skeleton frame—
Learn the shape, and you'll know the name!
[Verse 2]
Carpals in the wrist, tarsals in the sole,
Cube-shaped little soldiers playing a small role,
No long reach, just an inch of sway,
Stability's their business, they don't run away,
Packed tight like gravel under a bridge,
Steady little blocks on a rolling ridge.
[Chorus]
Long bones lever, short bones stack,
Flat bones armor your chest and back,
Irregular twists where the puzzle bends,
Sesamoid hides where a tendon ends,
Five shapes building one skeleton frame—
Learn the shape, and you'll know the name!
[Verse 3]
The skull's a vault, the ribs a cage of bars,
Sternum and scapula, broad shields like a knight's,
Flat as a shingle, wide for muscle to hold,
Guarding the lungs, the heart, the story untold,
Vertebrae stack and the sphenoid bends and twists,
Irregular shapes where plain geometry quits,
Flat bones don't spiral, they crack like a plate—
A single sharp line, a clean splintered fate.
[Verse 4]
Patella's the champion, riding the knee,
Born inside a tendon, small as can be,
Named for the sesame, that tiny tan seed,
Tucked into rope where a pulley might need,
It glides, it guards, it multiplies your throw,
A pebble in a sling, patient and slow.
[Bridge]
Diaphysis the shaft, epiphysis the end,
Metaphysis flares where the two blend,
Physis is the plate where a child grows tall,
Seal it too soon and you've stunted the call,
Long bones spiral, flat bones splinter and crack,
Listen for crepitus—that grinding, crackling snap,
A whispered rasp when broken edges grind and meet,
Crepitus speaking through muscle, bone, and heat.
[Chorus]
Long bones lever, short bones stack,
Flat bones armor your chest and back,
Irregular twists where the puzzle bends,
Sesamoid hides where a tendon ends,
Five shapes building one skeleton frame—
Learn the shape, and you'll know the name!
[Outro]
Lever, block, shield, puzzle, seed—
Five shapes answer every body's need,
Snap or spiral, crack or splinter clean,
Now you know the shape behind the scene.
