Which of the following describes the palm turned upward?

The term that describes the palm turned upward is supination. Supination refers specifically to the rotation of the forearm and hand so that the palm faces upward or forward. This position is often used in various exercises and movements, as it allows for optimal grip and positioning of the hand for lifting or manipulating objects.

In contrast, pronation refers to the rotation of the forearm in the opposite direction, resulting in the palm facing downward. Adduction refers to the movement of a limb or body part toward the midline of the body, while hypertension is not relevant in this context; it refers to an excessive extension of a joint beyond its normal range of motion. Thus, supination is distinctly characterized by the upward-facing palm.
