Below this point, the cauda equina—a bundle of nerve roots resembling a horse's tail—descends through the lumbar cistern to exit at their respective intervertebral foramina. The location of these muscle groups relative to the spine dictates their function; for instance, the quadratus lumborum acts as a fixator for the 12th rib and assists in maintaining intra-abdominal pressure during heavy lifting.

Running parallel to these processes is the sacrospinalis muscle group, which gives the back its characteristic contour. Surface Anatomy and the Vertebral Column The thoracic and lumbar vertebrae create the bony framework of the back, with the spinous processes forming the visible and palpable midline ridge.
The cord does not extend the entire length of the vertebral column; in adults, it typically ends at the L1 or L2 vertebra, forming the conus medullaris. Clinical Correlation and Pathophysiology.

The location of the kidneys can often be approximated by drawing horizontal lines at the levels of the 12th rib; the upper pole of the right kidney typically sits at the T12 vertebra, while the left kidney is slightly higher due to the presence of the liver. The pancreas, though primarily an abdominal organ, has a tail that extends toward the spleen, lying transversely across the posterior abdominal wall at the level of the first and second lumbar vertebrae.
