[Verse 1]
Picture a vault with no door and no key,
eight curved plates fit snug like armor at sea,
frontal stands watch where your eyebrows begin,
the rest of the dome keeps the thinking safe within,
not one bone alone, no, it takes the whole crew,
a fused stone jigsaw holding all of you.
[Chorus]
Frontal up front, two parietal walls,
occipital's the cape where the back of your head falls,
temporal pair ticking time at your ears,
sphenoid's the wedge, ethmoid sifts out your fears,
eight bones banded, locked at every seam,
that's the cranial vault, holding up the dream.
[Verse 2]
Parietal borrows its name straight from "paries,"
plain Latin for wall, nothing fancy, no fees,
two of them arch like a barrel above,
cradling the brain that you're thinking with and love,
occipital's root, "ob" fused with "caput,"
Latin for head, so it's "against the head," got it,
it's the back plate, the base where your skull meets your spine,
guarding the stem where your senses align.
[Verse 3]
Temporal bones flank your ears, left and right,
"tempus" means time, here's the old folklore bite,
first silver hairs sprout right there at the side,
so the bone near your hearing also marks time's slow ride,
it cradles the hammer, the anvil, the stirrup too,
three tiny ear bones doing work most folks never knew.
[Chorus]
Frontal up front, two parietal walls,
occipital's the cape where the back of your head falls,
temporal pair ticking time at your ears,
sphenoid's the wedge, ethmoid sifts out your fears,
eight bones banded, locked at every seam,
that's the cranial vault, holding up the dream.
[Verse 4]
Trace the fault lines where the baby plates grew,
coronal rides ear to ear like a crown pulled askew,
sagittal splits straight, an arrow shot through the crown,
lambdoid zigzags low like the Greek letter down,
these aren't cracks, they're joints stitched to flex and to grow,
soft in the cradle, then harden up slow.
[Bridge]
But find that thin spot they call the pterion,
four bones kiss there, fragile as paper, thin as a yawn,
underneath runs the middle meningeal's thread,
one hard knock there and the clock starts to race in your head,
blood pools quick, it's called epidural dread,
doctors watch that temple like a fuse near a bed.
[Chorus]
Frontal up front, two parietal walls,
occipital's the cape where the back of your head falls,
temporal pair ticking time at your ears,
sphenoid's the wedge, ethmoid sifts out your fears,
eight bones banded, locked at every seam,
that's the cranial vault, holding up the dream.
[Outro]
Eight bones fused into one quiet dome,
frontal, parietal, occipital home,
temporal's ticking, sphenoid wedged in tight,
ethmoid sifts softly, holding your sight,
the vault stands guard so the story can start,
the face bones come next, but the brain is the art.
