Lumbar

In anatomy, lumbar is an adjective that means of or pertaining to the abdominal segment of the torso, between the diaphragm and the sacrum (pelvis). The five verterbrae in the lumbar region are the largest and strongest in the spinal column. In most mammals, the lumbar region of the spine curves outward; this is called lordosis. The actual spinal cord terminates between vertebrate one and two of this series. The nervous tissue that extends below this point are individual strands that collectively form the cauda equina.
