They have a thick, broad spinous process with sets of articular processes that project between the pedicles and laminae. The transverse processes are long, slender, bony projections. These are similar to the ribs found in the thoracic vertebrae but are shorter and smaller. In the lower lumbar vertebrae, there are three tubercles present: the costiform process, mammillary process, and accessory process. The bony processes of the lumbar vertebrae provide muscle attachment points, such as for the psoas major and multifidus muscles.
