Which term is associated with the posterior region between the hipbones?

The term that refers to the posterior region between the hipbones is sacral. The sacral area is located at the base of the spine and is associated with the sacrum, a triangular bone that connects the two hip bones. This region plays a crucial role in the structure of the pelvis and supports the weight of the upper body when sitting or standing.

The popliteal region is actually located at the back of the knee, which is not relevant to the region between the hipbones. The sternal area pertains to the chest region, specifically the breastbone, and does not relate to the hip area. The umbilical region refers to the area around the navel, situated in the anterior abdominal wall. Each of these terms describes specific anatomical areas of the body, but the sacral term specifically designates the area between the hipbones at the posterior aspect.
