Anatomy of the Lumbar Spine: Where Are the L1-L5 Vertebrae Located?

As a fetus, vertebral segments directly relate to spinal cord segments. As an adult, the spinal column grows longer than the spinal cord, and they no longer relate to one another. The spinal cord ends around the L1 or L2 vertebrae in adults, forming the conus medullaris. The horsetail-shaped area, which extends past the conus medullaris, is called the cauda equina.
