Full L2 (2nd Lumbar Vertebra) Description
[Continued from above] . . . muscles that create balance, flexion, and extension in the lower back. Additionally, the spinous process is fairly rectangular and extends more or less horizontally from the rest of the bone. The rest of the vertebral arch includes wide, strong laminae; very large pedicles notched above and below; long and thin transverse processes; and a triangular central vertebral foramen (that is a bit larger than that of the L1 vertebra) for passage of the spinal cord. A superior articular process presents a facet that articulates with the L1 vertebra above, and an inferior articular process and facet articulates likewise with the superior process of the L3, with each process emanating from the vertebral arch between the pedicle and transverse process. The transverse processes lack foramina, which differentiates the lumbar vertebrae from the other true vertebrae.
