[Verse 1]
Skull plates locked like jigsaw pieces fused,
sutures welded shut, no wiggle room is used.
That's a fibrous joint, the strongest, stillest kind,
a tooth sits snug in socket, root and bone entwined.
No slide, no give, call it synarthrosis talking,
an immovable union, built for zero walking.
[Chorus]
Where bones meet, that's the story told,
fibrous, cartilage, synovial — three ways to hold.
Synarthrosis locked, amphi bends a touch,
diarthrosis swings and loves it way too much.
Ligament ties bone to bone, tendon grips the muscle crew,
cartilage caps the ends so the joint can glide on through.
[Verse 2]
Pubic symphysis, a disc of rubbery glue,
holding both hip bones together when you walk on through.
Your spinal discs are stacked like jelly-filled donuts,
amphiarthrosis bending — slightly, never won't.
Not frozen solid, not wild and unchained,
middle-ground motion, cartilage-restrained.
[Chorus]
Where bones meet, that's the story told,
fibrous, cartilage, synovial — three ways to hold.
Synarthrosis locked, amphi bends a touch,
diarthrosis swings and loves it way too much.
Ligament ties bone to bone, tendon grips the muscle crew,
cartilage caps the ends so the joint can glide on through.
[Verse 3]
Now the knee, the shoulder — synovial, roomy, loose,
a fluid-filled capsule built for reckless use.
Diarthrosis dancing, rotating, full range,
ligament straps keep the bony partners arranged.
Tendon yanks the lever when the muscle starts to strain,
articular cartilage keeps the grinding bones from pain.
[Bridge]
Donald Unger cracked one hand for sixty years straight,
left hand silent, right hand popped on every date.
Just gas bubbles bursting in the fluid — a tiny snap,
cavitation fizzing, nothing sinister, no trap.
He checked both hands, found no arthritis anywhere,
two thousand nine, the Ig Nobel judges cheered.
[Verse 4]
But stretch a ligament too far past its station,
a sprain shows up uninvited, swelling's celebration.
Dislocate the shoulder, the ball jumps off its track,
avulsion rips a chip of bone before it's dragged back.
Every injury story starts right where the bones connect,
know your joints and you'll predict the break you should expect.
[Chorus]
Where bones meet, that's the story told,
fibrous, cartilage, synovial — three ways to hold.
Synarthrosis locked, amphi bends a touch,
diarthrosis swings and loves it way too much.
Ligament ties bone to bone, tendon grips the muscle crew,
cartilage caps the ends so the joint can glide on through.
[Outro]
Fibrous, cartilage, synovial glide,
synarthrosis, amphi, diarthrosis ride.
Where bones meet is where the body bends or stays,
learn the junction, understand the break always.
