In anatomical position, which thumb points to the left side of the paper?

In anatomical position, the body is standing upright, facing forward, with arms at the sides and palms facing forward. In this position, the left thumb naturally points to the left side of the body, while the right thumb points to the right side. Therefore, if you are referring to a piece of paper oriented in front of you, the right hand's thumb, which is positioned on the right side of the body and pointing outward, effectively points to the left side of the paper. This understanding of orientation is critical for accurately describing body parts in anatomy, as it relies on a consistent framework (the anatomical position) that does not change regardless of the observer's perspective.
