Which term means foot or palm upward?

Supination refers to the movement that results in the palm of the hand or the sole of the foot facing upward. This term is derived from the Latin word "supinare," which means to bend backward. In the context of anatomy and physiology, supination involves rotating the forearm, so the palm faces upward, and it can also be applied to the feet, where supination describes the movement of the foot to a position where the sole turns inward and the heel raises slightly.

This contrasts sharply with pronation, which refers to the opposite movement, where the palm or foot turns downward or inward. Elevation and protraction are unrelated to the orientation of the palm or foot; elevation involves raising a body part, while protraction refers to moving a body part forward. Hence, supination is the correct term that specifically describes the position of the foot or palm facing upward.
