Fifth lumbar vertebra, Vertebra lumbalis V;
median section.
Note the characteristic wedge-shape of the body of the
fifth lumbar vertebra.
* Region of the vertebral arch between the superior and inferior articular
process. Here in the fifth and less frequently in the fourth lum bar vertebra
a cleft, bridged by connective tissue (spondylolysisl can be formed. This is
probably caused by local bending stress. As a consequence, the superior
vertebra may slip (olisthesisl onto the inferior vertebra (spondylolisthesis).
