Thelumbar regionis sometimes referred to as the lowerspine, or as an area of the back in its proximity.

Inhuman anatomythe fivelumbar vertebrae(vertebrae in the lumbar region of the back) are the largest and strongest in the movable part of thespinal column,可以区分缺乏foramenin thetransverse process, and by the absence of facets on the sides of the body. In mostmammalsthe lumbar region of the spine curves outward.

The actualspinal cord(Angelamedulla spinalis) terminates between vertebrae one and two of this series, called L1 and L2. Thenervoustissue that extends below this point are individual strands that collectively form thecauda equina. In between each lumbar vertebra anerveroot exits, and these nerve roots come together again to form the largest single nerve in thehuman bodythesciatic nerve. The sciatic nerve runs through the back of each leg and into the feet. This is why a disorder of the low back that affects a nerve root, such as aspinal disc herniation, can cause pain that radiates along the sciatic nerve (sciatica) down into the foot.

There are severalmusclesin the low back that assist with rotation, flexibility and strength. These muscles are susceptible to injury, especially while lifting heavy objects, or lifting while twisting. A low backmuscle straincan be extremely painful but will usually heal within a few days or weeks.

The lumbar portion of the spine bears the most body weight and also provides the most flexibility, a combination that makes it susceptible to injury and wear and tear over time. This is whylow back painis so prevalent.
