From Head to Toe, 19

Head to Toe:

Boning Up on the Bones of the Body

Spine (a): cervical bones

These seven bones along your neck

Are how you keep your head erect.

Yes, cervical (the name for them)—

The name comes not from any whim

But from the word in Latin, so

A lot to Romans we still owe!

These are the smallest in the spine—

Take care of yours—and I will mine!
