What term refers to the area of the lower back?

The term that refers to the area of the lower back is "lumbar." The lumbar region is specifically situated between the thoracic region (which is the upper back and corresponds to the rib cage) and the pelvic region (located at the very bottom of the vertebral column). This region consists of five vertebrae, labeled L1 to L5, and is crucial for supporting the weight of the upper body and allowing for movement and flexibility. The lumbar spine is also often subject to strain and injury due to its role in bearing weight and its mobility. Recognizing the anatomical significance of the lumbar region is essential for understanding both human anatomy and the mechanics involved in activities such as lifting or bending.
