Transverse process of thoracic vertebra ...
Other Terms: Processus transversus, Processus transversus vertebrae
These club-like processes project dorsolaterally from the junction of the lamina and pedicle. Near their rounded extremity is a smooth articular surface for articulation with the tubercle of the rib. This is absent on the eleventh and twelfth vertebra. Besides supporting the ribs, these processes provide attachment for many muscles and ligaments.
Process is a term used in anatomy to describe a projection on a bone. It comes from the Latin pro- meaning forward and cessus for gone. It is an old term that can be traced back to the writings of the early anatomist Celsus.
