What is a vertabrey?

It seems there might be a typo in your question. If you meant "vertebra," it refers to the individual bones that make up the vertebral column, or spine, in humans and other vertebrates. Each vertebra is separated by intervertebral discs and plays a crucial role in supporting the body, protecting the spinal cord, and allowing for flexibility and movement. If you meant something else by "vertabrey," please provide additional context!
