From Wikipedia, the free encyclopedia. In tetrapod anatomy, lumbar is an adjective that means of or pertaining to the abdominal segment of the torso, between the diaphragm and the sacrum. The lumbar region is sometimes referred to as the lower spine, or as an area of the back in its proximity.
The size of the lumbar spine allows for more space for nerves to move about. When people experience pain in their spine it often occurs in the lumbar region. This is because the lumbar spine is connected to your pelvis, which is where most weight bearing and body movement takes place.
