They are stacked on top of each other with a disc in between each one. All of the vertebral bodies act as a support column to hold up the spine. Cervical vertebrae. In vertebrates, cervical vertebrae (singular: vertebra) are those vertebrae immediately inferior to the skull.
Thoracic vertebrae in all mammalian species are defined as those vertebrae that also carry a pair of ribs, and lie caudal to the cervical vertebrae. Further caudally follow the lumbar vertebrae, which also belong to the trunk, but do not carry ribs. In reptiles, all trunk vertebrae carry ribs and are called dorsal vertebrae. Artificial Anatomy.
