An animal possessing a backbone or spinal column made of vertebrae that protects the spinal cord. This group includes fish, amphibians, reptiles, birds, and mammals.
From Latin 'vertebra' meaning 'joint of the spine,' derived from 'vertere' (to turn). The term reflects the articulated nature of the spine, which allows flexible movement while providing structural support.
The vertebrate spine is essentially a sophisticated engineering marvel that solved the problem of how to be both flexible and strong! Each vertebra is designed to distribute weight while allowing the spinal cord—our body's main information highway—to remain protected during movement.
