Full T9 (9th Thoracic Vertebra) Description
[Continued from above] . . . Otherwise, the T9 greatly resembles the T2-T8 vertebrae in having a centrum (ventral body) in the shape of a heart, with flat articular surfaces above and below, creating a joint with the T8 vertebra above and the T10 below, with cartilaginous intervertebral discs between to cushion the joints and provide support to the spine. The T9 has a smaller (and circular) vertebral foramen than the vertebrae above it. Its laminae are large and overlap with the T10 vertebra.
