Thoracic vertebrae 11 and 12 are different from other thoracic vertebrae because their transverse processes do not have facets that articulate with the tubercles of the ribs. This is because these vertebrae do not have corresponding pairs of ribs attached to them, so they do not need the articulating facets.
