Ravens are vertebrates, which means they have a backbone or spinal column. The backbone is a flexible rod-like structure that runs along the back of the animal and provides support for the body. It also protects the spinal cord, which is a bundle of nerves that runs through the backbone and carries messages between the brain and the rest of the body.
Ravens have a relatively long backbone, which allows them to move their heads and necks freely. They also have a number of ribs that attach to the backbone and help to protect the heart and lungs.
