Origin and history of vertebra

vertebra(n.)

in anatomy and zoology, "bone of the spine, segment of the backbone," early 15c., from Latin vertebra "joint or articulation of the body, joint of the spine" (plural vertebræ), perhaps from vertere "to turn" (from PIE root *wer- (2) "to turn, bend") + instrumental suffix -bra.

The notion would be the spine as the "hinge" of the body. The vertebrae for "the backbone" is attested from 1620s. Vertebrum was used from late 14c. in English as "round head of the thigh bone."
