What is the term for the position of the body standing upright, facing forward, with arms at the sides and palms facing forward?

The term for the position of the body described as standing upright, facing forward, with arms at the sides and palms facing forward is known as the Anatomic Position. This position serves as a standard reference point in anatomy for describing the locations and relationships of different body parts. In the Anatomic Position, the body is oriented so that various directional terms (like anterior, posterior, medial, and lateral) can be consistently applied, enhancing communication and understanding in the field of anatomy and physiology.

In contrast, the Supine Position refers to lying on the back, while the Prone Position refers to lying face down. The Neutral Position, although it sounds similar, is generally not a widely recognized term in anatomical terminology as a standard reference. Therefore, the Anatomic Position is the correct term for the upright stance described in the question.
