The lumbar vertebrae (vertebrae lumbales) have a large bean-shaped body. The height of the body increases in the direction from I to V vertebra. Vertebral openings are large, almost triangular in shape. The transverse processes are located almost in the frontal plane. The spinous processes are flat, short, with thickened tips. The articular surfaces of the upper articular processes are directed medially, and the lower ones are lateral. On each upper articular process there is an insignificant tubercle - mastoid processus mamillaris.
