Anatomical terms of bone

The transverse processes (la. processus transversus) of a vertebra, two in number, project one at either side from the point where the lamina joins the pedicle, between the superior and inferior articular processes. They serve for the attachment of muscles and ligaments.

The transverse processes of thoracic vertebrae articulate with the tubercle of rib.[1]

The transverse process of a lumbar vertebra is also called costal[2][3] or costiform process[4] (processus costiforme or processus costalis in Latin) by some anatomists, because it corresponds to a rudimentary rib (costa) which, as opposed to the thorax, is not developed in the lumbar region.[5][4]
