This portion of the spine is meant to support the rib cage and provide proper posture for the body. The 12 vertebrae that make up the thoracic spine, commonly referred to as T1-T12, each have two facet joint sets â one set on the top and one set on the bottom â that are responsible for providing the middle back with flexibility and strength.
In other animals the number of thoracic vertebrae can vary greatly; for example, most marsupials have 13, but koalas have only 11. 12 to 15 is common among mammals, with 18 to 20 in horses, tapirs, rhinoceroses, and elephants, and extremes in mammals are marked by certain sloths with 25 and cetaceans with 9.y convention, the human thoracic vertebrae are numbered T1-T12, with the first one (T1) located closest to the skull and the others going down the spine towards the lumbar region.
