Atlas and axis
- The atlas does not have a vertebral body equivalent, and the axis has an extra projection, the odontoid process, above the vertebral body. This dentary process was originally the vertebral body of the atlas. During development, what should have been the body of atlas fused with the body of axis. The axis is the last one to be placed in the urn, called "Buddha" when the bones are placed in the urn after cremation.
