The size of the vertebral body boosts from L1 to L5, a sign of the increasing loads that each lower lumbar vertebra takes in. Of note, the L5 vertebra has the heaviest body, smallest spinous process, and thickest transverse procedure. The intervertebral discal surface area of an adult vertebra consists of a ring of cortical bone peripherally termed the epiphysial ring.

Each vertebral arch is composed of 2 pedicles, 2 laminae, and 7 different bony processes (1 spinous, 4 articular, 2 transverse) (see the following image), collaborated by aspect joints and ligaments. Back vertebrae are identified by massive bodies and robust spinous and transverse processes.
