The thoracic vertebrae become larger toward the caudal end and the circular vertebral foramina smaller, which holds true for the T11 vertebra. However, the T11 and T12 vertebrae differ from the other thoracic vertebrae in lacking facets for the ribs on their transversemycontentbreak processes, which additionally are shorter here; also, they are more similar in size and function to the lumbar vertebrae. Additionally, the articular surface for the rib is located on the pedicle rather than the centrum and is significantly larger than for the superior thoracic vertebrae. A short, more horizontal spinous process and shorter transverse processes likewise differentiate it.
