Which region is described as the lower back?

The lumbar region refers specifically to the lower back of the human body, encompassing the area between the rib cage and the pelvis. It is composed of five vertebrae, which are larger and stronger than those in the thoracic and cervical regions, reflecting the greater weight-bearing and support role they play. This part of the spine is crucial for supporting the upper body, facilitating movement, and providing stability during various activities.

In contrast, the thoracic region pertains to the middle back and is attached to the ribcage, while the cervical region is located in the neck area and consists of seven vertebrae that support the head. The cephalic region refers to the head and face, which is entirely distinct from the lower back area. Understanding the distinctions between these anatomical regions is essential in various health and medical fields, particularly when addressing concerns related to back pain, injury, or musculoskeletal health.
