How would you best describe the structure at the end of the spine?

Answer 1

Physicians use a code to number each of the 24 vertebrae in the spine. The low back officially begins with the lumbar region of the spine directly below the cervical and thoracic regions and directly above the sacrum. The lumbar vertebrae, L1-L5, are most frequently involved in Back pain because these vertebrae carry the most amount of body weight and are subject to the largest forces and stresses along the spine
