The spinous process is especially well-developed, and is directed forward. The articular processes are rotated upward, so that their surfaces are directed more nearly toward, or away from, the median plane, instead of to the dorsal or ventral surface. The anterior articular surfaces are borne on the bases of stout, upwardly-directed mamillary processes (processus mamillares). The latter are most characteristic of the lumbar vertebrae, but may be seen to arise in the posterior thoracic.
