33 bones playing telephone between your brain and your toes, badly.
means The flexible chain of vertebrae running from skull to tailbone that supports the body and houses the spinal cord.
from "Spinal" comes from Latin spina, meaning thorn or prickle, later extended to mean backbone — likely because the knobby vertebrae, poking up under skin, looked like a row of thorns. "Column" comes from Latin columna, a pillar, used since antiquity for anything upright and load-bearing. Put together, the phrase is a Latin-rooted bit of plain description: a thorny pillar holding you up.
