Which ISS body region is assigned to the forehead?

The correct designation for the forehead within the context of the International Society of Sports (ISS) body region taxonomy is the Face. This classification is based on anatomical delineations where the face encompasses all features including the forehead, eyes, cheeks, and jaw.

The forehead specifically is a part of the facial region, which also emphasizes its direct relation to the overall structure and aesthetics of the face. In contrast, the Head/Neck region is broader, encompassing all parts of the head including the face, but when asked specifically about the forehead, the most accurate and precise classification is within the Face category.

In general, it's important to understand how different body parts are categorized in anatomical references or classifications, as they provide clarity for communication in fields such as medicine, fitness, and sports science.
