Final answer:
The abdominal region is anterior to the gluteal region, meaning it is positioned toward the front of the body compared to the back where the gluteal region is.
Step-by-step explanation:
In anatomical terms, the abdominal region is anterior (or ventral) to the gluteal region. Anterior describes the front or direction toward the front of the body. The abdominal region is located on the front side of the human body, whereas the gluteal region is on the back side or the posterior aspect of the body. Therefore, the correct directional term to describe the location of the abdominal region in comparison to the gluteal region is anterior.
