Which vertebral region is located at the lower back?

The lumbar region is located in the lower back and consists of five lumbar vertebrae, labeled L1 through L5. This region plays a crucial role in supporting the weight of the upper body and allowing for a wide range of movements, including bending and twisting. The lumbar vertebrae are larger and stronger than those in the cervical and thoracic regions, which is necessary to accommodate the increased stress and load in the lower back area. The intervertebral discs in this region also provide cushioning and flexibility, contributing to the overall mobility of the spine while maintaining stability. Understanding the anatomical significance of the lumbar region is essential for recognizing issues such as lower back pain or injury.
